American Birding Association Field Notes Mid-Atlantic Region P.O. Box 71 North Beach, MD 20714 16 December 1997 Dear Friend, With the close of another reporting season for Field Notes, I am writing to remind you to send in your sightings for the season as soon as possible. A few trends are of particular interest this season. It seemed to me that Red-breasted Nuthatches were in evidence in late August and September, seemed to disappear in October, and were back again in force in November. Was this the case in your observations? Were there differences in habitat use in September and November? Please report all your Lesser Black-backed Gull sightings, complete with ages. I spent a lot of time at a couple of local landfills and saw some interesting shifts in the age composition of Lesser Black-backeds there. And finally, we were graced by another winter finch flight! Please report ALL sightings of grosbeaks, siskins, redpolls, and especially crossbills to us, so we can sketch the best picture of the flight as a whole. Continue to watch your favorite pine woods for Red Crossbills, any spruces, hemlocks, and even pines for White-winged Crossbills, weedy fields for redpolls, and, of course, your feeders! There will likely be more excitement in store: Pine Grosbeaks are on the move in the Northeast and Great Lakes regions and winter finch flights continue to materialize through February. Since we do appear to be getting a lot of winter finches, please take special note of them this upcoming winter so we can continue to monitor the flight. Habitat and behavioral notes will be especially valuable and may help local observers know where to look in the next invasion year. I'd also like to encourage any observers who are capable, to try to obtain recordings of the Red Crossbill call notes. As many of you are probably aware, Red Crossbill is now believed to be a superspecies divided into about 8 different types. Main differences appear to be only in body size, bill size, and call note. Anyone interested in the current beliefs about this (these?) species might check out the Crossbill Web Page at Http://research.amnh.org/ornithology/crossbills/. It has descriptions, range, maps, habitat descriptions, sonograms, and recordings of the call notes, the relevant measurements, and more. To my knowledge, no one has yet checked the specimens from the Region in museums, but based on range considerations, it is likely that we might find Types 1, 2, 3, and 4 in the Region. With some quality recordings this year, perhaps we will be able to piece together this question. Obviously, the quality equipment will produce better recordings, but even low quality recording may be sufficient for identification. Also, please document any Pine Grosbeak and Hoary Redpoll reports for the state records committees, and note that the Maryland/D.C. Records Committee (MD/DCRC) also requires documentation for White-winged Crossbills. This season was an interesting and exciting one, and for the first time since leaving for Bowdoin College four years ago, I was in the Region to enjoy it. I assisted Deanna Dawson at her Patuxent Wildlife Research Center banding station. It was my first experience with banding, and seeing the birds in the hand provided quite a different perspective and taught me a lot. I also had the opportunity to spend a lot of time in the field and my personal highlights from the season are too many to mention here. Among many memorable personal successes this season were: regularly and easily finding American Golden-plovers, sometimes in large flocks (the most being 123), in plowed fields on the Upper Eastern Shore; finding Buff-breasted Sandpipers at five locations, at both turf farms and plowed field situations with the Golden-Plovers; Red-necked Phalaropes and a Sanderling at the Ridgely Sewage Plant, Caroline County, MD, on several visits there; an abundance of shorebirds, including Baird's, Buff-breasted, and White-rumped Sandpipers, American Golden-Plover, and a lone American Avocet, as well as good camaraderie and a chance to touch base with Virginia birders at VSO's annual Chincoteague weekend; three different Eared Grebes, each at its respective sewage pond in Dorchester, Washington, and Allegany Counties; a lone adult and a family of five white Ross's Geese in one Berlin, Worcester County, MD, Snow Goose flock; a hybrid family near Starr, Queen Anne's county, that included a pure adult white morph Goss's, its blue hybrid mate, and four young (three white, one blue) which were all Ross's size and shape, with grinning patches; a white adult Ross's Goose among Canada Geese near Bristol, Anne Arundel County; adding Common Tern, Yellow-bellied Flycatcher, American Coot, and Gadwall to my yard list bringing the total to 206 (not quite up to Harry's yet.but there's still time!); successful chases of the Fork-tailed Flycatcher near Mechanicsville, Saint Mary's County, the King Eider reported at Cambridge at Thanksgiving, and a first-winter Franklin's Gull found by Jim Stasz in Upper Marlboro on my birthday, November 3; as well as a Loggerhead Shrike, 2 Connecticut Warblers, a Glaucous Gull, 3 Greater White-fronted Geese, a Eurasian Wigeon, late White-rumped and Spotted Sandpipers and Red-eyed and Solitary Vireos, and a host of other great birds. There is truly no substitute for time afield. One major task we have taken upon ourselves is the computerization of all reports. Each sighting is entered into a LOTUS 1-2-3*.WK1 file as a row item which includes species, #, date, location, county, state, observer, compiler, and comments as column entries. To date, we have compiled about 15,000 lines of data for the Fall 1997 Season. We include not only the rare or unusual sightings, but every report of a common species. The decline in House Finch over the past two years in a prime example of why this is valuable. Two years ago they were still quite common in most areas and reported frequently on daily checklists. Since the outbreak of conjunctivitis the decline has been quite noticeable. Though entering all the reports truly is a monumental undertaking, all the effort pays off when it comes time to write the Season Report. I can easily sort the list by species to view all reports in taxonomic order, by date to show major migration days, by observer or locality, or by any combination of such features. It is not too early to start planning for the next North American Migration Count scheduled for May 9, 1998. This continent-wide one-day tally produces exciting information about the status of migration. For more information, contact me, or Jim Stasz, Coordinator of NAMC, P.O.
