Coot species that migrate do so at night. The American coot has been observed rarely in Britain and Ireland, while the Eurasian coot is found across Asia, Australia and parts of Africa. In southern Louisiana, the coot is referred to by the French name "poule d'eau", which translates into English as "water hen".
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night.

A common pattern in North America is clockwise migration, where birds flying North tend to be further West, and flying South tend to shift Eastwards. Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone.
Look out for birds across Iowa on Thursday night. Hundreds of thousands of birds will fly through the state to head south for the winter.
During migration, common nighthawks may travel 2,500 to 6,800 kilometres (1,600 to 4,200 mi). They migrate by day or night in loose flocks, frequently numbering in the thousands; [6] flocks have not been observed with a visible leader. The enormous distance travelled between breeding grounds and wintering range is one of the North America's ...
The study found a mismatch between earlier spring green up and the timing of migration for some long-distance travelers, leaving birds such as the black-throated blue, “out of sync."
A variety of small, colorful birds are making their way to Kentucky soon. Here’s advice from a local birding expert on what to look for. ‘Blindingly gorgeous’ spring birds will migrate to KY ...
