Migration strategies in the avian world are often compared at the species level and evaluated relative to general ecology and constraints such as molting and breeding timetables. The advancement of tracking technology provides an opportunity to explore variation in more specific migration tactics within species and their populations as it relates to demographic and environmental factors throughout the annual cycle. We compare migration timing among 4 populations of Bobolink (Dolichonyx oryzivorus) from across the breeding range using data from light-level geolocators. The date of departure from the breeding grounds and the duration of southbound migration differed among breeding …

Weak Effects Of Geolocators On Small Birds: A Meta-Analysis Controlled For Phylogeny And Publication Bias, Vojtěch Brlík, Noah G. Perlut

Currently, the deployment of tracking devices is one of the most frequently used approaches to study movement ecology of birds. Recent miniaturization of light-level geolocators enabled studying small bird species whose migratory patterns were widely unknown. However, geolocators may reduce vital rates in tagged birds and may bias obtained movement data. There is a need for a thorough assessment of the potential tag effects on small birds, as previous meta-analyses did not evaluate unpublished data and impact of multiple life-history traits, focused mainly on large species and the number of published studies tagging small birds has increased substantially. We quantitatively …
Latest Documented Fall Record Of Oporornis Agilis (Connecticut Warbler) In North America, Noah G. Perlut
Latest Documented Fall Record Of Oporornis Agilis (Connecticut Warbler) In North America, Noah G. Perlut
Environmental Studies Faculty Publications
On 11 November 2017, a male hatch-year Oporornis agilis (Connecticut Warbler) was killed by a Felis catus (Domestic Cat) in Scarborough, Cumberland County, ME. This specimen, housed in the University of New England ornithological collection, is the latest documented fall record of this species in North America.
