By altering the definition of the word "harm" as used by the Endangered Species Act, the Trump administration may limit how wildlife is protected in the United States. Environmental groups are suing.

Analysis of North American landbirds compares their latitudinal, elevational and phenological responses to climate change. Species have tracked 33% of current temperature change, with phenological cha...

The authors use a critically underutilized resource—bird banding data—to quantify and forecast changes in spring and fall migration across North America to ask the question of how migrants respond to...

In many social animals, females mate with multiple males, but the adaptive value of female extra-pair mating is not fully understood. Here, we test...

Wings with an elongated shape or larger surface area are associated with increased flight efficiency in a wide range of animals from insects to birds.…

In birds, the hand-wing index is a morphological trait that can be used as a proxy for flight efficiency. Here the authors examine variation of hand-wing index in over 10,000 bird species, finding tha...

Abstract. Convergent evolution is widely regarded as a signature of adaptation. However, testing the adaptive consequences of convergent phenotypes is chal

The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds. Many studies focu....

This tiny, plump-bodied, big-headed bird is a familiar woodland resident and backyard visitor in the northern U.S. and Canada. Gray overall with light buffy flanks and a contrasting head pattern: black cap, white cheek, and black throat. Short, stubby bill is used for hammering open seeds. Often the core of mixed flocks of songbirds. Visits feeders. Nearly identical to Carolina Chickadee, but range barely overlaps. Especially note voice, brighter white on wings, and buffier flanks on Black-capped. Beware that hybrids occur frequently in the overlap zone and some are best left unidentified.
