Interesting Fact: Tree Swallows line their nests with feathers, and they seem to display or even play with these feathers during the early nesting season. A bird flies above the nest with a feather held in its bill; sometimes this leads to chases, and sometimes the bird drops the feather, causing an aerial free-for-all to see which bird retrieves it.

You can tune a guitar, but you can’t tuna fish.
Interesting Fact: Gravel rooftops attract Killdeer for nesting, but can be dangerous places to raise a brood. Chicks may be unable to leave a roof because of high parapets and screened drain openings. Adults eventually lure chicks off the roof, which can be dangerous – although one set of chicks survived a leap from a seven-story building. ( https://www.allaboutbirds.org/guide/Killdeer )
Interesting Fact: Tree Swallows have helped researchers make major advances in several branches of ecology, and they are among the best-studied bird species in North America. Still, we know little about their lives during migration and winter. ( https://www.allaboutbirds.org/guide/Tree_Swallow/lifehistory )

Interesting Fact: The breeding habitat of the canvasback is in North Americaprairie potholes. The bulky nest is built from vegetation in a marsh and lined with down. Loss of nesting habitat has caused populations to decline. The canvasback usually takes a new mate each year, pairing in late winter on ocean bays. It prefers to nest over water on permanent prairie marshes surrounded by emergent vegetation, such as cattails and bulrushes, which provide protective cover. Other important breeding areas are the subarctic river deltas in Saskatchewan and the interior of Alaska. ( https://en.wikipedia.org/wiki/Canvasback )
Interesting Fact: The oldest Bufflehead on record was at least 18 years and 8 months old. It was caught and re-released by a bird bander in New York in 1975. ( https://www.allaboutbirds.org/guide/Bufflehead/lifehistory )
Interesting Fact: It used to be a strictly coastal bird in winter, seldom leaving tidal estuaries, where it feeds on eel-grass (Zostera marina) and the seaweed, sea lettuce (Ulva). On the east coast of North America, the inclusion of sea lettuce is a recent change to their diet, brought about by a blight on eelgrass in 1931. This resulted in the near-extirpation of the brant. The few that survived changed their diet to include sea lettuce until the eelgrass eventually began to return. Brants have maintained this diet ever since as a survival strategy. In recent decades, it has started using agricultural land a short distance inland, feeding extensively on grass and winter-sown cereals. This may be behavior learned by following other species of geese. Food resource pressure may also be important in forcing this change, as the world population has risen over 10-fold to 400,000-500,000 by the mid-1980s, possibly reaching the carrying capacity of the estuaries. In the breeding season, it uses low-lying wet coastal tundra for both breeding and feeding. The nest is bowl-shaped, lined with grass and down, in an elevated location, often in a small pond.
