- Cowbirds need to grow up alongside two host nestlings — no more and no less — to maximize their own survival
2022-02-18 - The College of LAS has selected winners of this year’s teaching and advising awards. Professors, graduate students, lecturers, and an advisor have been honored for their service."The College of LAS is enormously proud of the recipients of this year's teaching and advising awards," said Venetria K. Patton, Harry E. Preble Dean of the College of LAS. "Teaching and advising has always required...
2021-10-22 - Nearly 20 new faculty have joined the College of LAS this fall, with their research and teaching interests ranging from African American religious diversity to the human brain and the role of law during periods of crisis. Daniel Miller is a new faculty member in the Department of Evolution, Ecology, and Behavior
2021-10-20 - Females spend more time at nest after hearing cowbird alarm Across North America, hundreds of bird species waste time and energy raising chicks that aren’t their own. They’re the victims of a “brood parasite” called the cowbird, which adds its own egg to their clutch, tricking another species into raising its offspring.
2021-10-12 - 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 Bell Lab investigated how changes in sperm and paternal care...
2021-10-07 - 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 cacophony of bird calls rings in my ears. In the distance, I see a waving band of neon pink – a flag...
2021-09-30 - 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.
2021-07-29 - 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.
2021-06-29 - 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 years—except that lately the species has arrived earlier.
2021-06-22 - 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 Elsevier's journal Neuroscience Letters, shows that the early exposure to salient acoustic...
2021-05-27 - Each year, Mayo Clinic invites around 180 undergraduates from across the nation to participate in their Summer Undergraduate Research Fellowship (SURF) program.
2021-04-08 - 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 eggs. Their study offers insight into some of the physical challenges the discriminating host birds...
2021-03-01 - 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 with her window, now laid on the ground below.
2021-02-05 - 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 this episode of the American Birding Podcast, PhD student ...
2021-02-04 - 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 2021-22 academic year. They were among 20 faculty members chosen across campus. Center for Advanced...
