Q: If I find a dead bird, can it be used for research or teaching? Q: Isn't it illegal for me to salvage dead birds? |
|
In practice, however, the local U.S. Fish and Wildlife Service office and the State Dept. of Fish and Wildlife allow the public to possess birds for the time needed to deliver them to an approved educational institution such as the Burke Museum. Thus, if you call one of these offices having found a dead bird, they will likely refer you to our Ornithology Division. You should not consider keeping the material for your own use.
Q: What should I do when I find a dead bird? You can attach information to a bird by tying a tag to its leg, or by including a note written in permanent pen or pencil. Place the bird in a sealed plastic bag (such as Ziploc), freeze it, and transport it to the Burke Museum at your earliest convenience. If needed, call the Ornithology Office (206) 543-1668 for further instructions. The Washington Ornithological Society also collects salvaged birds for the Burke at its monthly meetings at the Center for Urban Horticulture. |

Drumming can occur year-round but is usually most intense during the breeding season, especially during early spring, when birds defend territories and attract mates. A male woodpecker may drum regularly until he attracts a female; females may also drum. For example, male European Great Spotted Woodpeckers, Dendrocopos major, change their rate of drumming dramatically once they have a mate and begin building a nest—from 500–600 to 100–200 times per day. While there is little you can do to stop drumming by a woodpecker, it will probably not last long. If it does, perhaps you can empathize—it often means the drummer has lost its mate. Species differences in drumming behavior |
Pileated Woodpeckers produce powerfully loud, longer-lasting (up to 3 sec.) bursts of drumming that often accelerate at the beginning and are given about once a minute. Red-breasted Sapsuckers produce a short rapid burst of taps followed by a slowing, irregular series of single or double taps. If you reproduce the sound of drumming accurately enough by rapping sticks on a hollow tree, often you can attract a drumming male to investigate the intruder in his territory. Excavation pecking |

The communal roosting of crows at night in the non-breeding season is particularly noticeable and sometimes disruptive. Crows probably roost communally for the same reason many other birds do—to avoid predation and share information about food resources. When crows are breeding, starting in about April in the Seattle area, they disperse onto territories, females stay on nests, and birds are generally less noticeable. However, as winter approaches crows often form huge roosts, where they congregate at sunset. They typically commute along regular flight paths, stopping at traditional pre-roosting sites along the way and often vocalizing loudly. Major roosts can reach truly astounding numbers: up to 2 million birds in places in the Midwest. In the morning, birds disperse and follow each other
to foraging sites. In general, larger roosts are associated with greater dispersal distances during the day—birds often fly many miles away to feed.

Crow Surveys and Banded Crows Ongoing surveys by the Seattle Audubon Society during its Christmas Bird Counts provide historic summaries of the growth of crow populations in this area. Researchers in the University of Washington's College of Forest Resources are also conducting a long-term study on crow behavior and population dynamics and have marked many individuals with color-bands. If you see a banded crow, please report it. |
