ABO relies on the help of many dedicated volunteers to operate the Creamer's Field Migration Station. During 1999, more than 80 people helped us check mist nets, untangle and carry birds to the banding station, record data, and repair nets. Migration fallouts are unpredictable, and we appreciate the patience of our volunteers when it seemed like we scheduled more people than the number of birds caught, or when a fallout surprised us and we were short handed. Our highly adaptable crew responded to slow days with lawn chairs and great conversation, and to busy days by racing from net to net without a break.
Although we are extremely grateful for the help of every volunteer who helped make this a fun and successful season, a few people deserve special recognition. Joyce Potter (profiled on this page) showed up twice weekly throughout the entire season, accumulating an amazing 241 hours of service and earning our 1999 Volunteer of the Year award. Without fail, dedicated "supermoms" Lorrie Hawkins, Kay Hackney, and Janlee Irving frequently brought their children to the station to experience environmental volunteerism at its finest. Special thanks go to junior volunteers Abby Hawkins, Luke DiCicco, Britta Irving, and Juliann Schamel for their enthusiasm and hard work. Finally, we thank those folks who earned their "five-year mug" for volunteering at least 40 hours/year for at least five years: Laurel Devaney, Gail Mayo, Ken Russell, Kristine Sowl, Judy Williams, and John Wright. Volunteers rule!

Bird banding is an important tool used to answer questions about birds. Recently, there has been an increase in the number of people using this valuable tool, however, skills and techniques have varied among bird banders. The North American Banding Council (NABC) was recently established to develop and promote a standard of sound and ethical bird-banding principles and techniques. The NABC consists of representatives from the most prominent North American ornithological societies and banding organizations.
The NABC has developed a bander- and trainer-certification program to evaluate knowledge, experience, and skills through a written test and hands-on demonstration. The first-ever certification process in the western United States was held in Reno, September 24, 1999. Anna-Marie Benson, ABO's Senior Biologist, passed the standards set by the NABC for the permittee and trainer levels after being evaluated by some of the most prominent people in the field (C.J. Ralph, Geoff Geupel, Kathy Klimkiewicz, Ken Burton, and Barbara Carlson, to name a few). Anna-Marie stated, "I wasn't expecting the process to be quite so intensive, although it is great to know that such high standards are being set."
The certification process is a great opportunity for people who are concerned that their banding skills meet North American standards. People can be certified at three different levels: assistant, permittee, and trainer. These designations will help people hiring field crews that require certain skills. The process is also an asset for anyone training bird banders. The Alaska Bird Observatory will be offering passerine bander certification courses during 2000; contact Anna-Marie Benson for more information.
The 100th annual Christmas Bird Count (CBC) sponsored by the National Audubon Society represents the oldest and largest wildlife survey in the world. Ornithologist Frank Chapman started the CBC in 1900 as an alternative to the annual "Side Hunt," a holiday tradition where the team that shot the most birds won the event. Chapman, an officer in the then budding Audubon Society, suggested that rather than slaughter birds, people count them instead. Today, more than 45,000 people participate in this annual, all-day census of early-winter bird populations.
The sample area for a CBC is a 15-mile diameter circle, and varying numbers of volunteers count all birds they see in the circle during a designated day within two weeks of 25 December. Although observers differ greatly in ability, effort is not standardized among years, and count circles are not randomly located, the CBC is viewed as a valuable supplement to the North American Breeding Bird Survey. To learn more about analyses of CBC data by the Biological Resources Division of the U.S. Geological Survey, visit the following web site: www.mbr.nbs.gov/bbs/int1cbc.html
Christmas Bird Counts are also great recreational and social events (many conclude with a potluck dinner to share results) during the cold, dark days of Alaska's winter. We encourage folks to get involved, whether it's to count birds visiting your feeder or to cover a pre-assigned area. Last year, 33 counts took place in Alaska, including ones in Cordova, Unalaska, Prudhoe Bay, King Salmon, and Kenny Lake. If you are interested in participating, contact your local CBC coordinator. A list of some contact numbers follows; others can be obtained by visiting

During the 1960's, Chandler Robbins of the Migratory Bird Population Station (now the Patuxent Environmental Science Center) in Laurel, Maryland, developed the concept of a continent-wide monitoring program for breeding birds. After testing the roadside survey methodology in 1965, the North American Breeding Bird Survey (BBS) was launched in 1966. By 1968, approximately 2,000 routes were established across the contiguous 48 states and southern Canada; during the 1980's, the BBS expanded into Alaska and the Yukon. Today there are approximately 3,700 active BBS routes in the continental U.S. and Canada.
The BBS was designed to provide a continental perspective of population change and it has been the primary tool used to detect declines in Neotropical migrant bird populations. Surveys are conducted along a 24.5-mile route during the peak of the nesting season. Fifty stops are made at 0.5-mile intervals, during which the observer records all birds seen or heard during a three-minute point count. Data are sent to the BBS office at Patuxent where it is computerized and analyzed. The survey produces an index of relative abundance, rather than a complete count of breeding bird populations, for those species well sampled by the BBS. You can view trend analyses and maps on the web at http://www.mbr.nbs.gov/bbs/
After completing routes in 1992 and 1994, the Alaska Bird Observatory re-entered the BBS scene this year. During June, we surveyed two routes along the Denali Highway and one route along Chena Hot Springs Road near Fairbanks. Although rising at 3 a.m. to start the counts was challenging, substantial bird activity and breath-taking scenery made it worthwhile. The Chena Hot Springs route passes through a corridor of riverine white spruce interspersed with ponds and patches of birch forest. We counted 39 species along this route, including 83 Swainson's Thrushes, 32 Alder Flycatchers, 51 Townsend's Warblers, and a Three-toed Woodpecker. The Denali Highway between Paxson and Cantwell hosts some wonderful but little-known birding opportunities as it meanders through rolling taiga and tundra and past rivers and countless ponds. We counted 55 species on two routes, including 26 Arctic Warblers, 55 Gray-cheeked Thrushes, 124 Wilson's Warblers, 152 White-crowned Sparrows, 24 White-winged Crossbills, and a smattering of Tundra Swans, Oldsquaw, scoters, Willow Ptarmigan, Arctic Terns, Lapland Longspurs, and redpolls.

Beginning in late August of this year, many Fairbanks-area birdwatchers were treated to unusually frequent appearances by a less-than-common visitor. Despite being listed as common in both the Checklist of Alaska Birds (Gibson 1999) and Field Checklist of Birds of Interior Alaska (Kessel 1986), Pine Siskins (Carduelis pinus) are rarely reported at Fairbanks-area bird feeders. The majority of the siskins have disappeared, but this seemed like a good time to take a closer look at these surprise visitors.
The "pine" in Pine Siskin refers to the trees in which these birds prefer to nest, but the origin of the name "siskin" is less clearly understood. The most likely derivation of "siskin" is from the Danish word sisgen or sidsken, or the Swedish word siska, both meaning "a chirper" (Choate 1985). Pine Siskins are usually observed in large flocks, with flocks of 50 - 200 birds common, and flocks up to 1,000 birds occasionally seen. Often loud choruses of tit-ih-tit and buzzy shreeees can be heard from these flocks (Terres 1980). The scientific name, Carduelis pinus, again reflects this species' preference to nest in conifers, as well as its relationship to a similar-looking, more common interior Alaska bird feeder visitor. Other members of the genus Carduelis include Common Redpolls, Hoary Redpolls, and the American Goldfinch. The name Carduelis is Latin for "goldfinch" and is derived from the Latin word Carduus, referring to thistle - the birds' favorite food (Choate 1985).
Pine Siskins are an irruptive species, yet are one of the top 10 most commonly found birds in Cornell's Project FeederWatch (see http://www.birdsource.org/pfw/). Irruptions are periodic movements of numbers of birds into unusual ranges for a season (Cox 1996). There are several irruptive, northern, seed-eating bird species, including Pine Grosbeaks, Common Redpolls, Red and White-winged Crossbills, and Red-breasted Nuthatches. It is believed that irruptions are triggered by food shortages (especially poor seed crops) on wintering grounds. For more information about winter bird irruptions, visit the BirdSource Irruptive Bird Survey web site at http://www.birdsource.org/ibs/.
Pine Siskins are generally found foraging in flocks during winter and are often associated with goldfinches and redpolls (Ehrlich et al. 1988; Kaufman 1996). Siskins tend to feed on seeds of alder, birch, and spruce, both in trees and on the ground. When foraging in flocks, these birds tend to start at the top of a tree and work their way downward in a group before flying to another tree to repeat this process. Individuals will sometimes hang upside down to reach seeds. Pine Siskins also tend to be attracted to salt and clay. Their attraction to road salts may exacerbate siskin deaths caused by automobiles (Ehrlich et al. 1988).
If you are lucky enough to have them in your area during winter, one of the best places to see Pine Siskins is at your bird feeder. These birds tend to prefer hanging or tube feeders with thistle or niger seed, but can also be attracted to black oil sunflower seeds and sunflower hearts. Water and birdbaths are also a possibility for attracting these chirping thistle-eaters.

Fairbanks is hosting the annual "Trees from the Heart" fundraising event December 5 at the Carlson Center. Local businesses and nonprofits decorate Christmas trees, which are then sold through a silent auction after a day of public viewing. ARCO Alaska, Inc. is again sponsoring the ABO tree, which looks to be as creative as last year's. Our tree's theme is "Things with Wings," so plan to see plenty of airplanes, butterflies, angels, dragonflies, and birds among the branches. Some of our favorite artists, including Betsy Chronic, Randall Compton, Janlee Irving, Sandy Jamieson, Dan Kennedy, Sara McDaniel, and Dave Totten are donating ornaments, and rumor has it there will be a limited-edition print tucked under the tree. We encourage ABO members to support our efforts by donating an ornament, coming to the event and voting for the "people's choice" award, and/or bidding on the tree. Call our office for more details.
