An efficient method of capturing Painted Buntings and other small granivorous passerines

To study survival in the eastern breeding population of the Painted Bunting (Passerina ciris), I developed a technique to capture a large sample of buntings for color marking with leg-bands. This involved the use of bird feeders and an array of three short mist nets located at 40 sites in four states, each site meeting five specific criteria. In five years of mist netting (1999-2003), 4174 captures (including recaptures) of Painted Buntings were made in 3393 net-hours or 123 captures per 100 net-hours. The technique proved to be effective and efficient, and may have broad application for capturing large numbers of small granivorous passerines.

Atlantic Flyway review: Region IV Piedmont-Coastal Plain, Fall 2007: Patuxent powerline right-of-way (390-0764)

This station operates at the Patuxent Research Refuge in a powerline right-of-way that bisects an upland deciduous forest. This area has been used for this purpose since 1980, except in the years 2004-2006. Twenty-six nets are arrayed along approximately one-half mile that runs generally on an east-west orientation. The habitat is marked by dense 4-6 foot high shrub foliage with very few trees of any height. Trees are purposely kept to a minimum within the right-of-way to avoid arcing with the powerlines. We operated seven days in August and November and 14 days in September and October for a total of 42 days, generally on a M/W I F schedule. Nets were opened · by 25-30 minutes before sunrise, and closed about 3.5 hours later. Weather did not have a significant impact on our operations. We did have a few mornings in late October when some nets were frozen, delaying their opening. Only once (13 Nov) did rain necessitate closing nets early.

Methods for capturing and banding Kalij Pheasants

We developed methods to capture and band Kalij Pheasants ( Lophura leucomelanos ) in their introduced range at Hawaii Volcanoes National Park, where they are not hunted and are relatively tame. Kalij were wary of foreign structures, such as traps, but readily took cracked corn bait and entered baited traps, provided they were introduced to them gradually. The majority of Kalij on the study site (53 of 64 birds) were captured using three trap designs: open-door trap, large box trap with hinged door, and drop trap. While the open-door trap was more mobile and easily set up in cramped forest spaces, only groups of as many as five birds could be captured at a time. The large, more cumber-some box traps captured groups of up to eight birds, whereas drop traps successfully captured only one bird at a time. Females were more difficult to capture than males. Band size was 7A for males and 6 for females.

Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns

San Francisco Bay, California, including its fringing marshes, supports a large and diverse water related avifauna (Grinnell and Wythe 19271 Sibley 1952, Gill 1973, 1977). Certain of man's alterations of the Bay's shallower wetlands have resulted in increased habitat diversity which has allowed colonization by several species of birds including some colonial nesting species. The extensive dikes associated with salt production and some areas of higher ground created by dredge spoils have provided increased tide-free substratum, some of it insular, suitable for nesting. The resulting numbers of Snowy Egrets ( Egretta thula) , Black-crowned Night Herons ( Nycticorax nycticorax ), Forster's Terns ( Sterna forsteri ), and Caspian Terns ( Sterna caspia ) using these areas now represent a significant portion of the northern California breeding populations of these species. In conjunction with a study of the breeding birds of the South San Francisco Bay Estuary (Gill 1973, 1977) from 1971 to 1973, we banded 187 Great Blue Herons ( Ardea herodias ), 1499 Snowy Egrets, 1615 Black-crowned Night Herons, 2943 Forster's Terns, and 743 Caspian Terns; often this represented a substantial portion of these species banded in the western states during these years (Table 1). Recoveries from these bandings through 1977 plus additional recoveries from a few earlier and some more recent bandings provide the data for this report on dispersal patterns and migration of San Francisco Bay produced herons, egrets, and terns.

Yellow birds stand out in a crowd

Highly visible auxiliary markers, such as neck collars, nasal saddles, patagial tags, and leg streamers, are used regularly and effectively with banding in studying migration and distribution of large birds (e.g. waterfowl, birds of prey, wading birds). Simply stated, a large bird can accommodate a marker that is large enough to be seen readily by an observer but still small enough not to alter behavior or impair flight (see Marion and Shamis 1977 for review). Such is not true with smaller birds, and consequently information on their migration routes and distribution is usually poorer than for larger birds. The use of colored leg bands increases the frequency of detection of small birds that have been banded; however, a large percentage of such marked birds is usually still overlooked. Only by using highly visible techniques, such as plumage dyes and bleaches in conjunction with leg bands, can one obtain significant numbers of sightings of small birds. Here we present information from sightings of large numbers of marked Dunlins ( Calidris alpina ) and Western Sandpipers ( C. mauri ) that dramatically demonstrates this.

Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD

Robbins Nest is located on the fall line one-half mile below Rocky Gorge Reservoir. During the fall migration, about 8 nets are run on the upper part of the 3 acres (edge of the lawn, the garden, under the Virginia Pines, and the upper edge of the mature oak woods that drop 80 feet to the Patuxent River). Foul weather on weekends, combined with commitments away from home, severely restricted this season's operation. August banding was limited to the weekend of the 23-24th. In September, all-day netting was conducted on the 6-7th and 20-21st, and this was supplemented with before- and after-work banding on 16 other days. October banding also was limited to 4 whole days and parts of 16 others.

Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)

Despite a 22% increase in net-hours, the number of new birds banded dropped 26% from 1977. The decrease was noted in each month and was spread among all of the commonest species, including summer residents, winter residents, permanent residents, and transients. The greatest declines were in Scarlet Tanager (84%), Blue Jay (78%), Red-eyed Vireo (67%), Gray Catbird (62%), Ruby-crowned Kinglet (60%}, Mrytle Warbler (56%), Gray-cheeked Thrush (55%), Wood Thrush (44%0, Cardinal (38%), and White-throated Sparrow (30%). Of these species, only the Scarlet Tanager and Myrtle Warbler had been banded in unusually large numbers in 1977. Partly offsetting the decreases were a few increases: Veery (from 4 to 22 birds), Black-and-white Warbler (3 to 12), and Ovenbird (15 to 34). The four species that had been singled out for mention last year as being victims of the severe winter weather in 1976-77 - the Winter and Carolina Wrens and the Golden- and Ruby-crowned Kinglets - fared no better in 1978. The first three were banded in almost identical nnmbers to 1977, and the Ruby-crown dropped again as indicated in the first paragraph.

Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)

Nets were operated at this suburban backyard station before and after work during the week, and all day on as many weekends as possible, from 23 August to 30 November. A trip to Spain interrupted banding in mid-September and accounted for the drop in both species and individuals banded. This also explains the 66% drop in Gray Catbirds, which was by far my most common species last year. As in past years, no netting was done within 15 m of the bird feeders, and no traps were baited until the nets were removed in December. White-throated Sparrows (9) and Carolina Chickadees (7) accounted for half of my returns. The oldest returns were a 6-year-old White-throated Sparrow and a 7-year-old Carolina Chickadee. The only species banded in unusually large numbers were American Robin and Black-throated Blue Warbler. A Red-shouldered Hawk and a Golden-winged Warbler raised the species total for this station to 112. Three birds remained here long enough to increase their weight by more than 30%: an HY female Black-and-white Warbler arrived on 29 August with a weight of 11.2 g and was last captured on 5 September with a weight of 17.1 g. It took an HY Ovenbird 24 days to increase from 20.8 g to the 28.2 g that it weighed when last caught on 13 October. A Swainson's Thrush, on the other hand, went from 36.5 g to 48.1 g between 10 and 14 October. Other heavy-weights were Hairy Woodpecker, 74.4 g; Blue Jay, 103.2 g; Gray Catbird, 46.4 g; Wood Thrush, 64.1 g; and White-eyed Vireo, 15.0 g.

Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 2001: Robbins Nest, Laurel, MD (390-0765)

I continue to band before and after work and all day on weekends on my two and a half acres along the Patuxent River gorge between highway 1-95 and the Laurel city limits. Our kids have long since flown the coop, so I have no one to run the station when I am out of town; thus, I miss some of the best flight days. The chief changes in habitat over the years have been replacement of pines by young deciduous growth, loss of dogwoods in the mature deciduous forest, and gradual replacement of lawn by shrubbery. To explore changes in fall migration patterns, I compared my banding totals for the first five years of systematic fall banding with those of the most recent five years. By coincidence the totals were nearly identical: 2175 birds in 1973-1977 and 2169 in 1997-2001. However, my net hour totals were vastly different: 9124 in the first five years compared with 26,284 for the current period. It took nearly 2.9 times the effort to catch the same number of birds I used to band. Next year, my 30 th , I'll be checking to see which species I am losing and which are maintaining their numbers. I had 35 returns of a dozen species, but all were either summer, winter, or permanent residents. The oldest this time was only four years old, a Gray Catbird. Eleven transients repeated on a subsequent day. The one longest in residence was a Gray-cheeked Thrush that l captured 10 times in 17 days; it weighed 31.0 g when banded and reached a maximum of 51.7 g 13 days later.

Post-spring migration colony-site prospecting by Roseate Terns (Sterna dougallii)

We recorded banded Roseate Terns (Sterna dougallii) and unbanded individuals mated to banded individuals in May and the first third of June in 2001 and 2002 to quantify post spring migration prospecting by this species at Falkner Island, Connecticut, USA. In 2001, more than one quarter: 34/125 (27.2%) of those observed by 19 May and 38/150 (25.3%) of those observed by 25 May did not remain at this colony site and went elsewhere to attempt breeding. In 2002, fewer terns were observed by 19 May, but an even higher percentage: 11/28 (39.3%) of those seen by 19 May and 58/151 (38.4%) of those seen by 25 May did not stay and nest. Our results demonstrate that a substantial proportion of the earliest arriving individuals at this site are prospecting and gathering information about local conditions before making a decision about going elsewhere to nest.

The U.S. Geological Survey Bird Banding Laboratory: an integrated scientific program supporting research and conservation of North American birds

The U.S. Geological Survey (USGS) Bird Banding Laboratory (BBL) was established in 1920 after ratification of the Migratory Bird Treaty Act with the United Kingdom in 1918. During World War II, the BBL was moved from Washington, D.C., to what is now the USGS Patuxent Wildlife Research Center (PWRC). The BBL issues permits and bands to permittees to band birds, records bird band recoveries or encounters primarily through telephone and Internet reporting, and manages more than 72 million banding records and more than 4.5 million records of encounters using state-of-the-art technologies. Moreover, the BBL also issues bands and manages banding and encounter data for the Canadian Bird Banding Office (BBO). Each year approximately 1 million bands are shipped from the BBL to banders in the United States and Canada, and nearly 100,000 encounter reports are entered into the BBL systems. Banding data are essential for regulatory programs, especially migratory waterfowl harvest regulations. The USGS BBL works closely with the U.S. Fish and Wildlife Service (USFWS) to develop regulations for the capture, handling, banding, and marking of birds. These regulations are published in the Code of Federal Regulations (CFR). In 2006, the BBL and the USFWS Division of Migratory Bird Management (DMBM) began a comprehensive revision of the banding regulations. The bird banding community has three major constituencies: Federal and State agency personnel involved in the management and conservation of bird populations that include the Flyway Councils, ornithological research scientists, and avocational banders. With increased demand for banding activities and relatively constant funding, a Federal Advisory Committee (Committee) was chartered and reviewed the BBL program in 2005. The final report of the Committee included six major goals and 58 specific recommendations, 47 of which have been addressed by the BBL. Specifically, the Committee recommended the BBL continue to support science, conservation, and management of birds through the use of banding and banding data and that the BBL be managed by the USGS and located at the USGS Patuxent Wildlife Research Center (PWRC) in Laurel, Maryland. Recommendations that have not been implemented include those already addressed by other organizations, as well as lower priority, such as developing a BBL business plan. The comprehensive review and recommendations of the Committee, the response of the BBL to address the Committee’s recommendations, and other improvements to its operations have positioned the BBL to provide a high level of service to the banding community. As new technologies are developed and incorporated into BBL operations, further efficiencies are expected to enable the BBL to continue to meet emerging scientific needs.

The North American Bird Banding Program: Into the 21st century

The authors examined the legal, scientific, and philosophical underpinnings of the North American Bird Banding Program [BBP], with emphasis on the U.S. Bird Banding Laboratory [BBL], but also considering the Canadian Bird Banding Office [BBO]. In this report, we review the value of banding data, enumerate and expand on tile principles under which any modern BBP should operate, and from them derive our recommendations. These are cast into a Mission Statement, a Role and Function Statement, and a series of specific recommendations addressing five areas: (1) permitting procedures and practices; (2) operational issues; (3) data management; (4) BBL organization and staffing; and (5) implementation. Our major tenets and recommendations are as follows: banding provides valuable data for numerous scientific, management, and educational purposes, and its benefits far outweigh necessary biological and fiscal costs, especially those incurred by the BBL and BBO; because of the value of banding data for management of avian resources, including both game and nongame birds, government support of the program is fully justified and appropriate; all banding data, if collected to appropriate standards, are potentially valuable; there are many ways to increase the value of banding data such as by endorsing, promoting, and applying competence and/or training standards for permit issuance; promoting bander participation in well-designed projects; and by encouraging the use of banding data for meta-analytical approaches; the BBL should apply, promote, and encourage such standards, participation, and approaches; the BBP should be driven by the needs of users, including scientists and managers; all exchange of data and most communication between banders and the BBL should become electronic in the near future; the computer system at the BBL should be modernized to one designed for a true client-server relationship and storage of data in on-line relational databases; the BBL should continue to maintain high quality control and editing standards and should strive to bring all data in the database up to current standards; however, the BBL should transfer a major portion of the responsibility for editing banding data to the bander by providing software that will permit the bander to edit his/her own data electronically before submission to the BBL; the BBL should build the capacity to store additional data tied to original band records able to be pre-edited and submitted electronically, such as recapture data, appropriate data from auxiliary marking (e.g. resightings of color-marked birds), and other data that gain value when pooled from many banders (e.g., measurements); however, the BBL should only accept such data if they are collected using standardized methods and as part of an established program designed to utilize such data; now is the time to consider options for implementing a Western Hemisphere banding program, with leadership from the BBL; the Patuxent Electronic Data Processing Section should become part of the BBL; additional scientific and technical staff must be added to the BBL; an Implementation Team should be formed to expedite our recommendations, following timetables outlined in this document.
