			<content:encoded><![CDATA[<p>Welcome to the 48th edition of Circus of the Spineless, a blog carnival dedicated to insects, arachnids, molluscs, crustaceans, worms and most anything else that wiggles, crawls or  flutters!  As the Circus nears the half-century mark, I feel privileged to be hosting for the first time.  As always, I&#8217;ve learned a lot from this month&#8217;s excellent submissions, and I hope you will too.  I&#8217;m sure you&#8217;ll agree that nothing compares to invertebrates when it comes to stimulating curiosity and interest in the natural world.  So without further ado, here are the posts, each introduced by a quote or image that I dusted off from the cabinet of scientific curiosity.  Enjoy!</p>

<blockquote><p>There&#8217;s the question of, why did I pick ants…? Why not  butterflies or whatever? And the answer is that they&#8217;re so abundant,  they&#8217;re easy to find, and they&#8217;re easy to study, and they&#8217;re so  interesting. They have social habits that differ from one kind of ant to  the next. You know, each kind of ant has almost the equivalent of a  different human culture. So each species is a wonderful object to study  in itself. In fact, I honestly can&#8217;t&#8230; understand why most people don&#8217;t  study ants.</p>

<p><strong>Steve at <a href="http://bluejaybarrens.blogspot.com/" target="_blank">Blue Jay Barrens</a> has been following a population of Edwards&#8217; Hairstreak (lycaenid) butterflies for over 20 years and was lucky enough last spring to discover <a href="http://bluejaybarrens.blogspot.com/2009/06/edwards-hairstreak-pupa.html" target="_blank">a cluster of pupae being tended by their ant protectors</a>.</strong></p>
<blockquote><p>The Lycaenidae offer an unusual opportunity to examine how herbivore enemies influence the evolution of larval diet.  The association of lycaenid butterflies with ants is generally perceived as a protective measure against larval and pupal enemies, particularly parasitoids, an extremely common aspect of lycaenid life histories…..  Six of the 10 subfamilies associate with ants, and to the extent that these groups are natural, there is a notable distinction in generic diversity between vascular plant-feeding groups with and without ants.  The two plant-feeding subfamilies of lycaenids associated with ants have diversified to 368 genera, while the three non-ant groups contain only 24 genera…..   The Lycaenidae represent nearly 40% of all known butterfly species…yet the ecology of their extraordinary ant relationships is not generally appreciated.</p>

<p><strong>Jill at <a href="http://www.nutcase007.blogspot.com" target="_blank">Count your chicken!  We&#8217;re taking over!</a> finds a <a href="http://nutcase007.blogspot.com/2010/02/trinidad-and-tobago-day-9-part-v-giant.html" target="_blank">monster land snail</a> during her trip to Trinidad and Tobago. </strong>Fortunately, it doesn&#8217;t appear to be the invasive Giant African Snail, <em>Achatina fulica</em>, that was <a href="http://www.health.gov.tt/news/newsitem.aspx?id=64" target="_blank">recently found in Trinidad</a>.</p>
<blockquote><p>&#8230;[T]he Amerindians of Tobago itself and neighbouring islands had quite different names for Tobago.  Two of these have been recorded in the documentary sources.  In the 1620s the Spanish writer Vázquez de Espinosa noted that « Tobago is called Urupaina in the Indian language, meaning big snail », adding that the island is « inhabited by Carib Indians, who used to ravage the island of Trinidad » (Espinosa 1942, p. 57). In the mid-seventeenth century Tobago is indeed reported to be inhabited by Amerindians ethnically belonging to the Cariban-speaking Kalina, i.e. Caribs who formerly lived also in North Trinidad and still inhabit parts of the Orinoco Valley and the Guianas (Boomert 1986, p. 14 ; Pelleprat 1965, pp. 36, 83-84). This would suggest that the name <em>Urupaina</em> represents a Cariban word. If so, it may be related to <em>oruape</em>, a generic term documented in 1789 as the Kalina word for « large snail » (Anonymous 1928, p. 221). Consequently, it can conjecturally be suggested that, like the Spanish, the Kalina Indians were struck by the characteristic contour of Tobago, seen from the ocean, which reminded them of the outlines of the large marine gastropods to be found in the Caribbean.</p>

			<content:encoded><![CDATA[<p>Welcome to the 113th Edition of <a href="http://10000birds.com/iandthebird" target="_blank">I and the Bird</a>!  I hope you enjoy your visit.</p>
<p>For this edition of I and the Bird, I decided to see what quotations from verse and literature would be invoked by the various submissions that I received.</p>
<p>In the spirit of several earlier IATB efforts that made use of found poetry (<a href="http://www.vianegativa.us/2007/05/i-and-the-bird-49-the-wordchaser/" target="_blank">Dave Bonta</a> and <a href="http://egretsnest.wordpress.com/2009/08/19/i-and-the-bird-108-group-poetry/" target="_blank">Liza Lee Miller</a> come to mind) and quotations (<a href="http://kiggavik.typepad.com/the_house_other_arctic_mu/2008/03/71---the-quotab.html" target="_blank">Clare Kines</a> did a nice job with this too), here&#8217;s what I put together this time around.  Mind you, it&#8217;s not easy to find literature relating to some of these species, so its quite a mixed bag, with sources as diverse as our contributors!</p>
<p>Coincidentally, while working on this post, I received a copy of a new anthology of bird poems, <a href="http://cup.columbia.edu/book/978-0-231-15084-2/bright-wings" target="_blank">Bright Wings: An Illustrated Anthology of Poems About Birds</a>, edited by Billy Collins, and illustrated by David Sibley.  I&#8217;ll be posting a review of this volume here soon &#8211; stop by next week to check it out.</p>

<blockquote><p>In their habits I cannot point out a single difference; — They are lively inquisitive, active run fast, frequent houses to pick the meat of the Tortoise, which is hung up, — sing tolerably well; are said to build a simple open nest. — are very tame, a character in common with the other birds: I imagined however its note or cry was rather different from the Thenca of Chile? — Are very abundant, over the whole Island; are chiefly tempted up into the high &amp; damp parts, by the houses &amp; cleared ground.</p>
<p>I have specimens from four of the larger Islands; the two above enumerated, and (3349: female. Albermarle Isd.) &amp; (3350: male: James Isd). — The specimens from Chatham &amp; Albermarle Isd appear to be the same; but the other two are different.

<p>Nate at <a href="http://thedrinkingbirdblog.com" target="_blank">The Drinking Bird</a> posts his thoughts about <a href="http://thedrinkingbirdblog.com/2009/11/02/the-future-of-bird-clubs/" target="_blank">revitalizing bird clubs for a new generation</a>.</p>
<blockquote><p>The first annual report of the Brush Hill Bird Club gives a list of thirty-seven bird clubs, located chiefly in New England. The annual report of the National Association of Audubon Societies gives a list of twenty bird clubs affiliated with the National Association. Mr. Ernest Harold Baynes, who has been the prime factor in this movement, has organized about sixty bird clubs; so that there are probably about one hundred bird clubs to be found in the United States.</p>
<p>The organization of a bird club enables those interested in birds to work more effectively than would be possible individually, and many people who are not acquainted with birds are interested in the opportunity for doing public service through the conservation of valuable birds. Interest may be aroused by having some one deliver a lecture on birds. A club may be organized at the close of such a lecture. Details regarding the methods to be used are given in Mr. Ernest Harold Baynes&#8217;s &#8220;Wild Bird Guests.&#8221;</p>
<p>One interesting result of these bird clubs has been the effect upon the communities in which they have been organized. Frequently a feeling of indifference to bird life has been changed to one of enthusiasm for bird-protection. In some cases the club has served as a center of general interest for the whole town and has been a means of arousing a community spirit.</p>

			<content:encoded><![CDATA[<p>I don&#8217;t know about you, but I love spiders.  While here in South Carolina, I was lucky to find and photograph several common and  attractive species.  This is the first installment in a series of posts in which I&#8217;ll highlight these species for the enjoyment of all of you arachnophiles out there!</p>
<p><strong>Lined Orbweaver, <em>Mangora gibberosa</em></strong><br />
Family: Araneidae</p>
<p>The Lined Orbweaver is a common spider that is widespread throughout the eastern United States.  In the southeast, it is especially abundant in grassy pond pine (<em>Pinus serotina</em>) savannas like the one shown below.</p>
<p><img class="aligncenter size-full wp-image-398" title="Pond Pine Savanna, Colleton County, SC" src="http://matthewsarver.com/wp-content/uploads/2009/08/2009-08-09_IMG_8427_edit_090816.JPG" alt="Pond Pine Savanna, Colleton County, SC" width="500" height="375" /></p>
<p>Strung among the grasses throughout the savanna are small, white, silken rings that are conspicuously evident against the sea of yellowish-green vegetation.  Upon closer examination, the white ring is at the center of a larger orb-web, the rest of which is invisible from a distance.  The white part of the web is called the stabilimentum, a structure found in the webs of many species of orb-weavers (Araneidae).</p>
<p><img class="aligncenter size-full wp-image-413" title="Lined Orb-weaver Web" src="http://matthewsarver.com/wp-content/uploads/2009/08/2009-08-09_IMG_8431_edit_090818.JPG" alt="Lined Orb-weaver Web" width="500" height="375" /></p>
<p>The purpose of the stabilimentum has been debated among arachnologists for a long time.  Hypotheses range from prey attraction to camoflauge for protection from predators to warning signals that keep megafauna from accidentally destroying webs.  Phylogenetic work suggests that web-decoration with stabilimenta evolved several different times in many araneid lineages (Scharff &amp; Coddington 1997).</p>
<p>My personal observations of the Lined Orb-weaver indicate that, in this species, one use of the stabilimentum is as a refuge from potential predators. When the web is approached closely or bumped, the spider quickly runs to the opposite side of the web from the intruder and hides behind the stabilimentum, which is sized perfectly to conceal the body of the spider.</p>
<p><img class="aligncenter size-full wp-image-396" title="Lined Orbweaver in web" src="http://matthewsarver.com/wp-content/uploads/2009/08/2009-08-09_IMG_8445_edit_090816.JPG" alt="Lined Orbweaver in web" width="500" height="375" /></p>
<p>How well this works, however, is open to debate.  Bruce et al. (2005) tested the visibility of stabilmentum silk to birds and bees.  They found that in one of their study species, the chromatic contrast between the spider and the silk was significant enough that the stabilmentum probably provided inefficient camoflauge from avian predators at close range.  It&#8217;s also possible that, since they are visible to bees and other insects, the small, discoid stabilimenta of the Lined Orb-weaver may attract prey to the web by mimicking flowers.</p>
<p>Whatever their adaptive significance, the sight of dozens of these small, silken rings dotting the vegetation is a fantastic experience for the naturalist willing to look closely.  The spider responsible for the web is pretty cool-looking as well!</p>

			<content:encoded><![CDATA[<p>The rash of unexpected Roseate Spoonbill sightings this summer has been a treat for birders up and down the east coast.  While northward movement of juveniles during post-breeding dispersal is known for the species, the numbers of birds involved and the extent of the northward movement this season is impressive.</p>
<p>According to the Birds of North America species account, spoonbills, &#8220;especially immatures, occasionally disperse great distances, but seasonal patterns of movement are poorly understood&#8221; (Dumas 2000).  In past years, the occasional individual has appeared as far north as Pennsylvania, Ohio, Wisconsin, and Nebraska.  Spoonbills regularly disperse in small numbers along the gulf coast in the states of Alabama and Mississippi, and north along the Atlantic coast to Georgia.  In 1972, a large movement of immatures occurred as far inland as Tennessee.  This summer, spoonbills have appeared in many eastern states, including Virginia, Delaware, and New Jersey.  In fact, I saw the bird that appeared <a title="Spoonbill" href="http://02b93fb.netsolhost.com/blog/?p=955" target="_blank">at Thousand Acre Marsh in Delaware last month</a>.</p>
<p>I&#8217;ve been fortunate to be in the Low Country of South Carolina for a couple of weeks, which is where I took the photo below.  These birds were part of a larger flock that contained at least 47 individuals.  The peak number of Spoonbills observed at this site this summer was 63 a few weeks ago.</p>

<p>I&#8217;m sitting in a john boat, taking this photo with a point-and-shoot camera, which gives an idea of how close I am to these birds.  They don&#8217;t seem too bothered, do they?  I keep wondering what drives these irruptions, and whether climate change is a contributing factor.  Spoonbill foraging is dependent on fluctuating water depths, so water level changes at foraging habitat in Florida might trigger large-scale movements.  Hopefully this year&#8217;s irruption (and its documentation by birders) will help us better understand the movements of this fascinating species.</p>

			<content:encoded><![CDATA[<p style="text-align: justify;">I&#8217;m going to be afield for most of the upcoming week with limited internet time, so I thought I&#8217;d get one more short post up before I leave.  First, I want to thank Jeff Gordon for his flattering <a title="Meet the Modern Naturalist" href="http://jeffreyagordon.com/2009/07/meet-the-modern-naturalist/" target="_blank">introduction of me over on his blog</a>.  Thanks too, to the folks at <a title="Nature Blog Network" href="http://natureblognetwork.com/" target="_blank">Nature Blog Network</a>, as well as many individual bloggers and blog readers who have taken the time to check out my site!</p>
<p style="text-align: justify;">As I mentioned <a title="Take Me to the River" href="http://matthewsarver.com/2009/07/take-me-to-the-river/" target="_blank">a few posts back</a>, I recently spent a week in the Catskills enjoying a wonderful river valley.  I&#8217;ll be sharing photos and nature tidbits from that trip in a series of posts.</p>
<p style="text-align: justify;">The first really fun observation I would like to share is the experience of watching female Common Mergansers shepherding their large broods of chicks while the youngsters learned to fish.  During our stay, the several local merganser broods would travel up or down the river, passing in front of our cabin only when we were inside, or around the back not paying attention!  One female had a group of 14 chicks, while another nearby female herded only 6 or 7.  (The largest known clutch is 19).</p>
<p style="text-align: justify;">
<p style="text-align: center;">
<div id="attachment_313" class="wp-caption aligncenter" style="width: 610px"><img class="size-full wp-image-313" title="The River with Our Cabin in the Background" src="http://matthewsarver.com/wp-content/uploads/2009/07/2009-07-06_IMG_2002_edit_090725.JPG" alt="This quiet stretch of river was a favored spot for Common Merganser fishing lessons.

<p style="text-align: justify;">At first, I was disappointed that I did not have the opportunity to photograph the merganser broods (a task that surely would have required me to build a blind by the river&#8217;s edge).  Later, though, I discovered that George Miksch Sutton had written this wonderful description of his encounters with merg broods on his trip down the Abitibi River with W.E. Clyde Todd in 1923:</p>
<blockquote>
<p style="text-align: justify;">The Abitibi was far more than a series of rapids, cataracts, and portage trails.  There were beautiful quiet stretches down which, aided by the strong current, we must have made up to five knots or more.  A notable feature of the birdlife were broods of half-grown common mergansers, each brood with its mother, all of them, mother and young alike, flightless, she in her late summer molt, they with their first major wing feathers only partly developed.  The close-knit companies dived when they saw the distant canoe approaching; when hard-pressed, however, they did not dive but rushed off half-standing, churning the water furiously, bodies weaving from side to side, wings not flailing the air but folded in tightly, thus protecting the stubby blood quills.  The noise of their sudden departure was startling, for it contrasted so sharply with the silence of the sequestered spots the birds so obviously enjoyed.  One fact about this truly common species, which the guides called the sawbill, impressed me greatly: not a single adult drake did we see during our descent of that mighty wild river!</p>
<p>-G.M. Sutton 1980. <em>Bird Student: an Autobiography</em> (p 125)</p></blockquote>
<div id="attachment_305" class="wp-caption aligncenter" style="width: 610px"><img class="size-full wp-image-305" title="Abitibi River, Ontario" src="http://matthewsarver.com/wp-content/uploads/2009/07/800px-Abitibi_River_edit_090725.JPG" alt="The Abitibi River at Iroquois Falls in northeastern Ontario.

<p style="text-align: justify;">Common Mergansers nest in tree cavities, often using old Pileated Woodpecker excavations, and also sometimes in crevices among rocks.  The chicks leave the nest and follow their mother to the water.  Since young chicks can&#8217;t fly until they are more than 2 months old, it&#8217;s a long summer for merganser moms.</p>
<p style="text-align: justify;">Females frequently brood parasitize other females of the same species by laying their eggs into the nest of the other female.  Another common, but poorly-studied phenomenon is the joining of several partly-grown broods under the care of a single female, knows as brood amalgamation.  While this happens frequently, it is unknown whether more aggressive females tend to &#8220;take over&#8221; other broods, or if the adoption of these chicks is simply the result of confusion on the part of the youngsters.</p>
<p style="text-align: justify;">Because of these complications, it is impossible to know exactly how many chicks are actually the offspring of their apparent mother.  None of this is the male&#8217;s problem, however, since as Sutton observed, they are nowhere to be seen during this period.  The pair bond apparently ends at incubation, but where do the males spend their time during mid-summer?  Do they hang out in trees, enjoying the cool mountain shade?</p>
<p style="text-align: justify;">According to A.C. Bent&#8217;s <em>Life Histories:</em></p>
<blockquote style="text-align: justify;"><p>The drakes desert the ducks and usually disappear from the breeding grounds entirely as soon as the eggs are laid, leaving the females to perform the duties of incubation and care for the young alone. In Newfoundland we saw only females on the lakes, where they were busy with family cares, but we saw plenty of males on the swift water rivers, playing in the rapids and fishing in the pools. Several observers in Maine have said that the males are not seen during the summer, but this may be due to the fact that the males are in eclipse plumage at this time and are very shy and retiring.</p></blockquote>
<p style="text-align: justify;">Can anyone out there shed some more light on the mystery of the missing merg males?</p>

			<content:encoded><![CDATA[<p>The House Sparrow (<em>Passer domesticus</em>) is one of those critters that birders love to hate.  The species makes a habit of usurping the nest sites of native species, especially bluebirds, and is therefore reviled by many a birder.</p>
<p>Initially released on this continent in the early 1850s in New York City and parts of New England, followed by many more releases across the U.S. and Canada during subsequent decades, the Old World sparrow rapidly established outposts on New World soils.  By the 1880s, the species was well-established in many cities, and its impacts on native avifauna were becoming obvious.  The bird that had once captivated the countless Americans who aided in its rapid spread had already worn out its welcome.</p>
<p>When watching these birds, it&#8217;s not difficult to see why they have persisted for the past century.  Their ability to thrive in urban settings, scavenging discarded french fries and other bits of refuse, is notorious.  Anyone who has watched House Sparrows making themselves at home inside warehouse stores or building sloppy nests of dry grass in every conceivable type of lamppost can attest to their adaptability.  I have to admit that I&#8217;m ambivalent about the species.  The scientist in me dislikes the impact of the House Sparrow on native birds, but the humanist in me loves the plucky spirit of these little tank-like city-dwellers.</p>
<p>Yesterday I witnessed an event that made me smile.  As I was about to get out of my car, I noticed a female House Sparrow that had flown to the ground nearby with something shiny and green in her bill.  I froze in the driver&#8217;s seat, window down, and watched.  Not ten feet away, the bird lit on some reddish landscaping gravel.  At this range I could tell what the mysterious object was: not one, but two Japanese Beetles!  The unfortunate beetles were attached to each other for the purposes of mating (a position referred to by entomologists as <em>in copulo</em>) and had no hope of disuniting in time for either to escape!  The sparrow settled down to lunch and quickly munched most of the first beetle of the pair, while the beetle&#8217;s mate could only wriggle in vain, still attached to the little that remained of its mate.  After briefly dropping the remaining beetle into the stones, the House Sparrow deftly picked up a piece of gravel, dropped it aside, and reclaimed its prey.</p>
<p>Two Japanese Beetles down, millions more to go.  One introduced pest species feasting on another.  Unfortunately, the energy-rich beetle innards, recycled, no doubt, from some gardener&#8217;s prized roses, were going to help produce more House Sparrows.</p>
<p>Such is the way of the urban jungle.  At least now I feel a little better about my guilty admiration for <em>Passer domesticus</em>.</p>
