American Kestrel Genoscape Project University of California Los Angeles, Boise State University, HawkWatch International, the American Kestrel Partnership FEATHER SAMPLING PROTOCOL Our plan - We have completed genomic sequencing, and are developing primers for assays of hundreds of samples. We will be building population specific migration maps within the next couple of years for American kestrels. Please help us collect samples from American kestrels across their range and annual cycle. Our request - We welcome feathers from migratory or resident kestrels, collected any time of the year, including breeding, migration, or winter. When body feathers are pulled, a small amount of skin cells remain attached to the quill of the feather. These skin cells are a valuable source of DNA that can be used to determine the population origin of an individual bird. We recommend that two body feathers be collected during the banding process from each bird. There is no need to collect feathers from the same individual more than once. And there is no need to collect samples from every nestling in a brood. One nestling will suffice. Necessary equipment and required permits To collect feathers, you will need labeled sampling envelopes (which we will send to you when you sign up) and a fine tip pen. In the US, to collect 4 body feathers from American kestrels, banders will need a federal bird banding permit from the USGS Bird Banding Laboratory (BBL) that gives permission to take, possess, and transport feather samples (for how to get permission from the USGS BBL please see below). In addition, you will likely need permission from the State agency where you are collecting feathers. For more information about State specific requirements please visit: http://naturalhistory.si.edu/birdnet/permit/index.html. You do not need a USFWS scientific collecting permit to collect body feathers from live birds while you are banding, if you have permission from the Bird Banding Lab (http://www.fws.gov/forms/3-200-7.pdf) In Canada, to collect 4 body feathers from American kestrels: 1) If you already have a Canadian Bird Banding Permit from the Canadian Bird Banding Office (Environment and Climate Change Canada) you will need to add proper authorization to take, possess and transport feather samples AND you will need a Scientific Collection permit from your province/territory 2) If you do not have a Canadian Bird Banding Permit, you can apply for a Scientific Collection/Wildlife Research permit from your province/territory to collect feather samples from American Kestrels
Countries outside of the United States and Canada will have different permit requirements to collect American Kestrel feathers depending on laws and regulations in that country. Please contact your local wildlife agency to determine requirements. If you are unsure whether you meet the above requirements, and would like help navigating the federal, state or international permitting systems, we can help! Please Contact Us ***Copies of federal bird banding permits and state permits must be included in sample shipment*** Collecting Feather Samples From live birds: To collect a sample, gently tease apart feathers on the belly/breast of the bird until you have a feather firmly between your thumb and finger as close to the body as possible. To pluck the feather, just hold them relatively close to the base, and pull quickly and gently. Ensure that you are pulling contour feathers, rather than down feathers, as these provide quality DNA (see pictures and diagram below). Do not touch the quill, as the DNA is extracted from the skin cells attached to it. Place the feathers, 4-5 total, from each bird into a labeled sampling envelope. Providing your own envelopes is fine, but please make sure each envelope contains the necessary data described below. American kestrel contour feathers (left) and down feathers (right). Please only collect contour feathers, as these provide quality DNA for genetic analyses.
Diagram of bird feather types. Please collect contour feathers from the belly or breast, as these provide the best quality DNA for genetic analyses. From carcasses: Feather samples from live birds are preferred, as they provide high quality DNA for analysis. However, feathers can be taken from kestrel carcasses in cases where the kestrel is recently deceased, but the collection method is slightly different. In these cases, please pull out a clump of feathers, ensuring that a visible amount of skin is attached to the tips. Please note that collection permits are still required whether feathers are taken from live or dead birds, and the number of feathers in the clump should be recorded. Feathers can be stored at room temperature. Please send sample shipments at the end of the field season (see instructions below). Required Data 1) On each envelope please provide the following information: Date (Please use letters for the month instead of numbers, e.g. Apr 25, 2016) Species Name Band Number Location (closest town, State/Province, country [eg: Boise, ID, USA]) Sex (male or female) Age code: adult (A; any non-nestling bird capable of flight) or nestling (N; birds found in the nest) [if nestling please record age in days in the UKN line] Please check yes for Breeding If samples are from an adult bird captured on the nest or at a territory, otherwise check No or UNK. Recapture If the bird was previously banded by you or another bander (yes) or the bird is newly banded (no)

Research Project Summary Using high-resolution genetic markers to reveal American Kestrel connectivity: towards understanding kestrel population declines and the impacts of climate change on raptor monitoring and management Summary American Kestrels (Falco sparverius) are declining for unknown reasons and studies regarding their rates of survival and migratory ecology are lacking. Further, patterns of bird migrations are changing both spatially and temporally because of climate change. Historically, the challenge for studying migrant ecology, the drivers of regional population declines, and the impacts of climate change has been an inability to link breeding, wintering, and migrant populations. Recently, Ruegg et al (2014) described a new single nucleotide polymorphism (SNP) based method for identifying populations of migratory birds at finer spatial scales than has previously been possible. By harnessing the power of this new SNP-based methodology we will finally be able to tackle long-standing questions in migrant ecology and population dynamics of the American Kestrel. Understanding the migratory connectivity of populations of American Kestrels, and how connectivity changes with climate, will allow us to: 1) identify the wintering grounds and migratory routes of declining breeding populations,2) test hypotheses about population change and 3) assess the impacts of climate change on the effectiveness of migration counts as a tool for monitoring raptor populations. To do this, we will need to collect DNA samples using plucked feathers from American kestrels across their range and throughout the annual cycle. Two to five body feathers will be gently plucked from the belly or back of the kestrel, stored in an envelope, and shipped to UCLA for analysis.

THE TIMELINE PROJECT Photographic Atlas of American Kestrel Nestling Development Introduction American Kestrels (Falco sparverius) are small, sexually dimorphic falcons sporting a distribution range in our region from Canada to Florida, with a few individuals being year-round inhabitants. After a largely monogamous courtship period ending in late March, female kestrels lay clutches of four to six eggs, with roughly one egg laid per day. Eggs hatch following an incubation period of about twenty-eight days. Once hatched, young nestlings develop to the point of fledging within a period of thirty to thirty-six days (personal observations). Literature references concerning kestrel development during this monthlong period however are scarce. The best guide in circulation that can aid in determining the age and gender of kestrel nestlings is that of Griggs and Steenhof (1993). The primary goal of this project is to clearly illustrate, through colored digital photographs and key measurements and observations, the developmental stages of typical male and female nestlings from time of hatching until fledging. Kestrel developmental variation previously has been correlated with numerous factors including: nestling gender, brood size, asynchronous hatching, parental conditioning (nutrition), and environmental effects (Gard and Bird 1992; Anderson 1993; Weibe and Bortolotti 1995; Dawson and Bortolotti 2000; Massemin et al. 2002). Due to these factors, our focus is to establish ranges of nestling development, which would take into consideration these sources of variation. As an auxiliary focus, this project hopes to aid field researchers working with the American Kestrels to provide an accurate at-a-glance method of aging young nestlings, and to better plan nest box visits for nestling banding. We hope that such a guide will be significant to those interested in Kestrel conservation, as well as those with a general interest in these falcons. 6
Methods Observations were taken on a study area near Hawk Mountain Sanctuary. The study area consists of 1500 square kilometers of open, sparsely wooded fields and farmland in Eastern Pennsylvania. Our site is 30 kilometers north of Reading and 30 kilometers west of Allentown, and includes portions of Berks, Lehigh, and Schuylkill counties. This location has been the site of several kestrel studies in the past (Rohrbaugh and Yahner 1997, Valdez et al. 2000). A conservation program, established by Hawk Mountain, has been maintained by Sanctuary staff and volunteers since 1987 (Rusbuldt et al. 2006). Kestrel broods used in this study nested in established nest boxes mounted to trees and, in a few cases, utility poles. Our study consisted of measuring and photographing nestlings from primarily three broods during June and early July of summer 2006. These three broods were visited on the day when the first nestling hatched until all of the nestlings fledged from the nest box. This provided us with an accurate starting age from which to base our subsequent measurements. These three broods comprised the entirety of our developmental measurement data, and supplied a total of 14 nestlings for our sample (with brood sizes of 4, 5, and 5 nestlings, respectively). Photographs were taken of other nestlings at different nest box locations, and their estimated ages were then determined using our observed data. Once the three study broods were identified and photographed at hatching, visits were made during early morning (9am-10:30am) every two days for additional photography. No measurements were taken prior to Day 9 due to a lack of significant primary feather sheaths. For each visit from Day 9 onward, in addition to the digital photographs, we measured with Vernier calipers the length of the fifth primary sheath, and after feather eruption the length of the fifth primary feather. Measurements were always taken from the left wing. Visual qualitative observations (color, feather patterns, gender determination) were noted on the nestlings appearance each visit. Nestlings were replaced in their nest boxes immediately following measurement sessions, which lasted approximately 15 minutes each. 7
General Observations Though our observations have conferred generalized indicators of nestling feather development, it must be stressed that variation is undoubtedly present. Variability factors such as brood size, hatching order, parental provisioning, nestling gender, and environment all readily affect nestling development, thus making a definitive description nigh impossible. The recommended developmental indicators outlined below pool our observations to account for some of this variability. Distinct observations of feather-sheath development are scarcely noticed until Day 9-10. Prior to this time, nestlings are quite small and completely covered with white down. Nestling size increases during this period, but is difficult to quantify due to the variability factors previously mentioned. Monitoring these nest boxes led us to conclude that aging young during this period is difficult and requires judgment. Accurate aging during this period increases with the observer s experience, as a gestalt is developed. Once nestlings have reached Day 9-10, key characteristics begin to present themselves. Most notably, feather sheaths begin to appear on the wings and shoulders at this age. Size continues to increase, but the nestlings are still completely down-covered. Patches of colored feathers may appear on the breast at Day 11-12, while the primary sheaths lengthen. Tail feather development is still absent at this stage. As early as Day 13-14, the primary flight feathers may begin to erupt, though they will be quite small if present. Gender determinations may or may not be able to be made on the basis of primary feather color if they have emerged. At this age tail, flank, and back feathers also begin to erupt. By Day 15-16, gender can be determined with certainty based on typical adult feather coloring and patterning on wings and breast feathers. Back and flank feather density increase as the tail and primaries lengthen. From Day 17-18 onward, size continually increases as the nestlings become more developed. Gender-specific tail banding as well as breast feather patterning emerges around Day 17-18. The percentage of bodily down steadily decreases as body feathers lengthen and overall feather density increases. Developmental rates of males and females are roughly equal until Day 21-22. During this last week of kestrel development prior to fledging, our observations show that male nestling feather development and size increase slightly more rapidly than females. 8

Photographic Atlas Recently hatched nestlings Hatch-Day 8: From the time of hatching until more than one week s time, nestlings are very small and are completely covered in white, patchy down. Size increases while down density decreases throughout this first week, although primary feather sheaths are completely absent at this stage. Lack of sheaths results in no clear indicator of development, making aging determinations in this range very difficult, especially from the age of Day 4 to 8. Aging in this range relies heavily on personal judgment and experience. When aging nestlings in this range, it is recommended to recheck the box within seven days to more accurately age nestlings. 10

A Ten day old nestlings Day 9-Day 10: Early into the second week of nestling life, very little developmental indicators are present. Though nestling size increases, they remain fully down covered. At this stage primary and back feather sheaths may be exposed, though small. If sheaths are present A, they can range from 0.6 to 1.0cm (Mean: 0.82cm). 13
B Eleven day old nestlings Day 11-Day 12: B During this stage of kestrel development, the prominent indicator of age is the exposure of the primary feather sheaths B,C, which are very distinct. Sheaths range at this age from 0.7 to 1.6cm (Mean: 1.14cm). Patches of colored feathers begin to emerge on the exterior regions of the breast. Nestlings backs remain completely down covered and tail feathers are absent. 14
C Eleven day old Male nestling Twelve day old Female nestling 15
F Fourteen day old Female nestling Day 13-Day 14: After two weeks of growth, sheaths are still the dominant anatomical feature with ranges from 1.4 to 2.0cm (Mean: 1.67cm). However, at this stage of development, other indicators of age also begin to emerge. Most notably, primary feathers begin to erupt after approximately two weeks, although at lengths less than 0.5cm (Mean: 0.28cm) D. Feathers on the tail E, flank F, and back also begin to erupt in this period. The feathers covering the ear opening (auriculars) begin to darken at this age, and constitute another distinctive indicator G. Depending on the brood, nestling gender may also be determined at this point by observation of blue-gray coloration on the male wing, and brown and black pigmentation on the female. 16
D G Fourteen day old nestlings E 17
I Sixteen day old Female nestling Day 15-Day 16: By the age of fifteen or sixteen days, nestling gender can be determined accurately as primary feathers have emerged (Range: 0.2 to 0.9cm, Mean: 0.48cm) and bear the gender-specific pigmentation seen in adult birds (blue-gray coloration of wings on males, brown and black on females) H. Exterior flank feathers increase in density, highlighting the spotting patterns of the males and the barring pattern of the females I. Back feathers have erupted rather significantly (~30% feathered) J, and increase in density across much of the dorsal region. 18
J H Sixteen day old Male nestling 19
O N Eighteen day old Male nestling Day 17-Day 18: At this stage, primary feathers continue to lengthen, ranging from 1.1 to 2.1cm (Mean: 1.53cm) K. Back feathers have filled in almost completely, with female alternating brown-and-black barring and the male rufous-and-black barring L. Flank and breast feathers continue to increase in density as they develop inwards from the exterior M. Male breast spotting and female barring increase in intensity. Tail feathers have increased significantly, and terminal banding appears (a white band in males, a dark band in females) N. Head remains largely down covered, though crown feathers do begin to emerge O. 20

R Twenty day old Female nestling Day 19-Day 20: In this time period, primary feathers continue to grow (Range: 2.0 to 3.2cm, Mean: 2.43cm) P, as do the back Q and breast feathers R, with these areas almost completely feather covered. Tail feathers lengthen, with females showing a second brown band S. Crown feather density increases, with little down remaining on the head. 23

Twenty-two day old Female nestling Day 21-Day 22: At three weeks of age, primary feathers range in length from 3.3 to 4.5cm (Mean: 3.71cm) T. Feathers on the back are almost fully developed (~95-100% feathered) U, as are breast feathers on males. Female breast feathering, it appears, is at a lower percentage than males. On a whole, more bodily down remains on females than males. Rufous patch on the males crown is distinctly visible by this age V. The tail has lengthened, and male banding pattern (white terminal, black midline, rufous base) W is present but no new bands have developed on the female. Head banding pattern of alternating dark and light feathers (mustache, auricular, nape) is highly pronounced X. 25

Twenty-three day old nestlings Day 23-Day 25: Toward the end of the kestrels time in their nest boxes, primary feathers reach lengths of 5.2 to 6.2cm (Mean: 5.75cm) Y. At this age, kestrels appear as miniature adults. Males appear more fully feathered and have less observable down than females, who still have noticeable patches of down on their lower breast and back, as well as upper wings. Tail feathers lengthen significantly, with females having five alternating bands at this age Z. 28

Twenty-eight day old Male nestling Post Day 25: From Day 25, no new measurements or photographs were purposely taken. However, a few candid photographs were taken when we surprised the nestlings still in the boxes. Boxes were monitored over the next week for signs of fledging. During this pre-fledging period, kestrel size increased as nestlings came to fully resemble miniature adults. The fourteen nestlings we observed fledged as early as Day 30 and as late as after Day 32. 31

Conclusion Following and photographing the development of these young American Kestrels has been an interesting and rewarding experience. It was a wonderful feeling seeing these birds struggle to exist, to observe their survival through to fledging, and to have the chance to be part of the American Kestrel population in Berks County. We hope we have the opportunity to observe these fledglings on our study site again within the next few breeding seasons. Finally, we hope that you, the reader, enjoyed this reference guide, and join in the support and conservation of wildlife in Pennsylvania and beyond, and that you are encouraged to learn more about the American Kestrel.
