Evolution, Ecology, and Behavior

Animals can influence their offspring through multiple signals starting from fertilization to after birth. However, researchers have seldom looked at how these different signals work together to influence behavior. In a new study, postdoctoral researcher Jennifer Hellmann in the...

It’s early morning, about 6 a.m. A light fog has settled over the marsh. I park my car, step out and double-check my backpack for all the necessary equipment before heading out. After a short walk on a narrow paved path, I veer into the unmarked marsh. Water pools around my muck boots and a...

Eye size likely plays a role in the contest between avian brood parasites – birds that lay their eggs in the nests of other species – and their hosts, who sometimes detect the foreign eggs and eject or abandon them, scientists report in the journal Biology Letters.

Dozens of online videos document an unusual behavior among tufted titmice and their closest bird kin. A bird will land on an unsuspecting mammal and, cautiously and stealthily, pluck out some of its hair.

The future of parasitic birds, which lay their eggs in other nests, is totally dependent on their hosts' ability to adjust to climate change. Imagine it’s spring in the year 2048. A Common Cuckoo returns from Africa to her breeding grounds in Europe, just as her ancestors have for thousands of...

Researchers at University of Illinois and City University of New York have recently carried out a study investigating the effects of early acoustic experiences on gene activation in songbirds. Their paper, published in...

Avian brood parasites lay their eggs in the nests of other bird species, forcing the hosts to do the hard work of raising the unrelated young. A team of scientists wanted to simulate the task of piercing an egg – a tactic that only a minority of host birds use to help grasp and eject the foreign...

Earlier this year, Emmarie Alexander, junior in ACES, sat at her desk in her room in her second-floor apartment, taking one of her Zoom classes. Alexander was startled by a loud noise, quickly turning her attention away from her class. She investigated the noise and realized a bird had collided...

Pity the poor cowbird. Under-appreciated at best and outright hated at worst, the cowbird and its parasitic nest ways certainly lend themselves to strong opinions. But it is a remarkable bird in its own right, capable of amazing developmental feats that allow it to fit into its very odd niche. In...

The Center for Advanced Study has appointed nine faculty members from the College of LAS, including associate Mark Hauber, as associates or fellows for the...
