<span style="font-family: "verdana" , sans-serif;">For five weeks during January and February, 2016, BSBO's Julie Shieldcastle worked with Costa Rica Bird Observatories banding neotropical migrants at two banding sites. Here is Julie's summary of the experience.</span><br />
<span style="font-family: "verdana" , sans-serif;"><br /></span>
<span style="font-family: "verdana" , sans-serif;">We have a tendency to think of the birds that pass through NW Ohio in the spring and fall as "our birds." Of course, some of them <i>will</i> stay in Ohio to breed, but the majority spend most of their time elsewhere, either breeding, during migration, or wintering
in some habitat south of the U.S. border. </span><br />
<span style="font-family: "verdana" , sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: "verdana" , sans-serif;">While in Costa Rica, I had the
opportunity to observe and/or capture with mist nets some of “our birds.” My goal was to observe some of the molt
strategies of these neotropical migrants during the alternate molt period we only get a small glimpse of. Just as not all of our birds breed in the same habitats up north, birds utilize a variety of wintering habitats down south. In five weeks of field work, I couldn't even consider relating to you where all species
reside in winter. </span><span style="font-family: "verdana" , sans-serif;">It was a small window of time and limited captures of migrants to make much sense of these intricate processes, but a valuable experience just the same.</span><span style="font-family: "verdana" , sans-serif;"> And i</span><span style="font-family: "verdana" , sans-serif;">t was educational to visit two distinctive habitats: the warm and humid Caribbean, and the cooler, damper cloud forest in the mountains of Cerra de Muerte.</span><br />

<div class="MsoNormal">
<span style="font-family: "verdana" , sans-serif;">Chestnut-sided Warblers (CSWA), from my brief experience, hang
out along the Caribbean Coast in mid-January. There were quite a few of them
observed foraging in the trees in the fragmented forest areas of Tortuguero. (It was interesting to find no evidence that the winter molt had even begun - which fits with this species' strategy of molting while in migration.) </span><br />

</tbody></table>
<span style="font-family: "verdana" , sans-serif;">Summer Tanagers were found in both sites I visited. </span><span style="font-family: "verdana" , sans-serif;">From the literature, males and females of migrant
species often winter in different locations, and different habitats, just as they do on the breeding grounds. Their behavior is just as complex here on the wintering grounds as it is on the
breeding grounds and possibly their migratory stopover locations, making it difficult to develop sound conservation strategies. <br /><br />One discovery that still stands out for me was when we weighed Chestnut-sided Warbler at the Tortuguero site. It had no fat and weighed 6.8 grams. This was a bit of a shock to me, since when we capture them here in Ohio during migration, they do have some amount of fat reserves and usually
weigh around 8-9 grams. I was concerned the scale to weigh the birds was not
working correctly, but it was checked and was calibrated properly. So, was the
CSWA at a normal weight for the wintering area? What happens when it is time to
migrate? Is the habitat good enough to build fat reserves for migration? Is there a critical level of volume or quality of habitats to provide enough food resources for them to
make a long distance migration? </span><br />

<span style="font-family: "verdana" , sans-serif;">The map of the Tennessee Warbler in the Costa Rica bird field guide shows them found throughout all of the country. Of the two places I was stationed, I
only observed them in the mountains. Could this represent a habitat shift, or are different habitats needed at different times during the winter and staging periods? Also found in the cloud
forest and associated cow pastures were Black-and-white Warblers (alternate molt completed already),
Golden-winged Warblers (GWWA), Wilson's Warblers, and a Louisiana Waterthrush.</span><br />

bird populations change, more research is required to keep us informed on the needs
of birds.</span><br />

We should never lose sight of the fact that if we are going to protect birds, we've got to protect and conserve habitat for birds throughout their life-cycle.</span><span style="font-size: small;"> </span></div>
<div style="text-align: left;">
<span style="font-size: small;"><br />In our promotion of birds at BSBO, we are fond of declaring that "BIRDS RULE." This thought took on a new meaning during my trip. Maybe, just maybe, if birds really did rule, this planet would be a little bit better for it.</span></div>

<span style="font-family: "verdana" , sans-serif;">In cooperation with Costa Rica Bird Observatories, BSBO’s
Julie Shieldcastle is currently undertaking an exciting opportunity, banding
birds at multiple research stations in Costa Rica. She’s not only learning
about tropical birds and their molt strategies, but also learning more about
the wintering habits of neotropical migrants which we extensively band in Ohio
during spring and fall migration. <o:p></o:p></span></div>

<span style="font-family: "verdana" , sans-serif;"><br /></span></div>
<div class="MsoNormal">
<span style="font-family: "verdana" , sans-serif;">During her time in Tortuguero, Julie not only experienced
the heat of coastal rainforests, but had the opportunity to work with Bright-rumped
Attila, Wedge-billed Woodcreeper, Red-capped Manakin, White-collared Manakin,
White-flanked Antwren, and the American Pygmy Kingfisher –which in her words, “…may
now be the coolest bird ever.” Neotropical migrants she encountered included
Chestnut-sided Warbler, Prothonotary Warbler, and Wood Thrush. <br /><br />It’s interesting
to note that the habitat these neotropical migrants were caught in resembles
that of their breeding habitat in the deciduous forests of the United States
and Canada: denser secondary and successional forest for the warblers, and mature
forest for the Wood Thrush. Traveling thousands of miles between two different ecozones, these birds are not arbitrarily picking breeding habitats in the Nearctic or wintering habitats in the Neotropic, but are selecting similarly aged and vegetated habitats. <o:p></o:p></span></div>

<span style="font-family: "verdana" , sans-serif;">Having departed Tortuguero last week, Julie is currently in
Madre Selva in the Talamanca Mountain Range near the southern end of Costa Rica, and will be residing there for three weeks. The Madre Selva area is
predominately cloud forest –tropical forest with low-level cloud cover– and is
known for its rich biodiversity, as well as being the center for birds endemic
to Costa Rica. <br /><br />At an elevation over 8,000 feet, the field station Julie will be
at is described as having an “alpine” feel, and is broken up by many pastures
among the surrounding cloud forest. With the opportunity to see birds such as
the Resplendent Quetzel, Collared Trogon, and even the Green-fronted Lancebill,
Julie has already worked with solitaires, brush-finches, tropical vireos and
warblers, woodcreepers, elaenias, and the Fiery-throated Hummingbird. <o:p></o:p></span></div>

<span style="font-family: "verdana" , sans-serif;">We are all familiar with the bright and vivid warblers of
spring migration, their calls on the breeding grounds in summer, and their often
confusing fall plumages; but what about winter? Where do these birds go once
they pass through Ohio in the fall, and what are they doing before they return
in May? <br /><br />As part of BSBO’s goal to connect our migration research on neotropical
migrants (e.g. warblers, vireos, tanagers) to a larger monitoring network and
promote conservation on breeding grounds, stopover habitat, and wintering grounds, a member of BSBO's research team is currently undertaking an exciting
opportunity in the rainforests of Costa Rica. With years of experience and as
one of BSBO’s premier bird banders, Julie Shieldcastle, in
cooperation with Costa Rica Bird Observatories, will be spending a month
between two monitoring stations as part of an ongoing study of land bird
populations in Costa Rica.</span><br />

knowledge of operating a large-scale banding station (such as BSBO’s Navarre
Marsh Banding Station) and work with the neotropical migrants our team is all too
familiar with from our banding work during spring and fall migration in Ohio.
<br /><br />As much as we know about the needs of these birds during migration and the
breeding season in North America, there still remains a gap of knowledge and
communication concerning neo-tropical migrants on their wintering grounds in
Central and South America. As exciting and educational as this experience will

these long-distance migrants. <o:p></o:p></span></div>

Temperature in the 50s.<br /><br /><br />*Sunday the 25th marked the last day of the fall banding season at the Navarre Marsh Banding Station, and it seems only fitting that a bird synonymous with winter (the American Tree Sparrow) would make its first appearance at the close of the season. We will continue our Navarre Marsh daily updates next Spring, beginning in April 2016. Until then, you can review all that has happened this past year by following the links below:<br /><br />For complete reports on Daily Banding Totals and Daily Bird Checklists (where you can see how many of each species was banded and what species were seen on each day) from the 2015 Fall and Spring banding seasons, click over to BSBO's website -<a href="http://www.bsbo.org/passerines.html">http://www.bsbo.org/passerines.html</a></span>BSBO Research Staffhttp://www.blogger.com/profile/06597452811778988415noreply@blogger.com0tag:blogger.com,1999:blog-6141809902537856409.post-45749987770145329362015-10-24T17:13:00.001-04:002015-10-24T17:13:36.137-04:00<span style="font-family: Verdana, sans-serif;">Daily Update: Navarre Marsh Banding Station<br />Date: Saturday, October 24, 2015 <br />Pictured: Swamp Sparrow<br /><br /><div class="separator" style="clear: both; text-align: center;">

Temperature in the 50s going to 60s.<br /><br />*Aging Rusty Blackbirds in the fall is a fairly easy task. Adults should have white/yellow eyes, and hatching-year birds should have mostly brown eyes. In fall, Male RUBLs (pictured today) tend to be darker with less "rust" on the edges of their feathers, and have a blue-green iridescence or gloss to the majority of their black feathers (especially the wing feathers). Fall Female RUBLs have noticeably more "rust" throughout their body feathers (especially the face) with an obvious pale eyebrow, and lack any gloss to their dark gray-black body feathers, which appear more matte or flat. <br />Mostly all of the rusty edging on the feathers will wear away during winter, and by spring, returning Rustys will be entirely black.</span>BSBO Research Staffhttp://www.blogger.com/profile/06597452811778988415noreply@blogger.com0tag:blogger.com,1999:blog-6141809902537856409.post-149391576606533692015-10-20T14:17:00.000-04:002015-10-20T14:17:02.385-04:00<span style="font-family: Verdana, sans-serif;">Daily Update: Navarre Marsh Banding Station<br />Date: Tuesday, October 20, 2015 <br />Pictured: Hermit Thrush<br /><br /><div class="separator" style="clear: both; text-align: center;">

In addition, as banders we are always trying to improve our skills in aging and sexing species that pass through the station.<br /><br />While the process of skulling or looking at the pneumatization of the skull makes for a generally definitive aging tool, some circumstances--</span><span style="font-family: Verdana, sans-serif;">weather conditions, number of birds waiting to be banded, and lighting conditions to "see" the windows in the skull of Hatch Year (HY) birds--</span><span style="font-family: Verdana, sans-serif;">can make this method sub-optimal. Use of plumage characteristics has become a more reliable alternative with many advantages. </span><br />
<span style="font-family: Verdana, sans-serif;"><br />Returning birds of known age and sex can make for a valuable comparison tool, as well as providing useful characteristics of aging and or sexing individual species. Here are a few examples of known-aged Common Yellowthroats (COYE).</span><br />

<span style="font-family: Verdana, sans-serif;">To properly age a bird, a bander utilizes multiple pieces of information to build a picture. There are a series of consistencies that include feather wear and shape (especially the primary coverts and alula), culmen coloration, and rectice shape. Becoming familiar with the molt patterns and timing of your target species can allow for more precise ageing of many species and provide detailed information for life cycle management of this valuable natural resource. <br /><br />As a note. there are always exceptions to every rule. For warblers, the Prothonotary Warbler bill coloration differences appear to be reversed for the age classes, with AHY bills presenting much lighter and pinkish in color. Banding is a constant learning process, but there are so many rewards--for us and for the birds. </span><span style="font-family: Verdana, sans-serif;">The better we understand species demographics the better we can ensure their future.</span><br />

A high pressure sitting over the Great Lakes the last third of September has stalled movement through the region. Other reports indicate a major movement off the western side of Lake Superior which may be a result of all the northeast wind we have encountered. Little early presence of the typical October species has occurred except for Winter Wren, with more than 10 banded in late September.<br /></span><span style="font-family: Verdana, sans-serif;">Navarre has been the site of many returning BLPWs during the fall migration season over the years, and this year is no exception. </span><span style="font-family: Verdana, sans-serif;">As of the first of October, we have encountered two Blackpolls previously banded in 2014. One was a Hatching Year (HY) bird banded on September 20, 2014 and captured again on September 27, 2015 as an After Hatching Year (AHY) male. The other Blackpoll was banded in Navarre on October 3, 2014 and returned to the same stopover site on September 28, this year. This puts great emphasis on the value of the Lake Erie Marsh region, arguably the most important stopover site for migrating Blackpoll Warblers in fall. </span><span style="font-family: Verdana, sans-serif;"><br /></span><br />

<span style="font-family: Verdana, sans-serif;">A big question has always centered on how many birds migrate through any area. While this is extremely difficult to determine for songbirds, the Blackpoll recaptures have offered a small window into this important question. Accepting a few <i>very big</i> assumptions, we have used the simplest of mark-recapture analysis tools (the Lincoln Index) to assess that volume. So far, using the recaptures, the number banded last year, and the number banded this year a point estimate of ~ 340,000 Blackpolls have passed along the beach ridge of Navarre this fall. Applying an approximate figure for the percentage of the stopover habitat Navarre represents to the marsh region, and you come up with nearly 7 million of these winged wonders visiting the Warbler Capital of the World so far </span><span style="font-family: Verdana, sans-serif;">this fall</span><span style="font-family: Verdana, sans-serif;">.</span><br />
