Timing of departure from natal areas by golden eagles is not constrained by acquisition of flight skills

open access: yesJournal of Avian Biology, 2023
The post‐fledging dependence period (PFDP), which extends from a fledgling's first flight out of the nest to its departure from the parents' territory, is crucial in the lifecycle of birds.

Hatching and fledging? A meta‐analysis of the performance effects of business incubators

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Business incubators are among the most widely implemented instruments to foster entrepreneurship. Yet empirical evidence on their effectiveness remains fragmented and often contradictory. Limited research systematically compares how different types of incubators influence multiple venture performance outcomes, including ...

Solar-powered radio tags reveal patterns of post-fledging site visitation in adult and juvenile Tree Swallows Tachycineta bicolor. [PDF]

open access: yesPLoS ONE, 2018
The availability of small, lightweight tracking devices enhances our ability to study birds during mobile phases of their lives. Tree Swallows Tachycineta bicolor, a model species of wild songbird, are well-studied during their breeding season; but our ...

Influence of temperatures during the nestling period on post-fledging survival of great tit Parus major in a Mediterranean habitat [PDF]

open access: yesJournal of Avian Biology, 2007
Survival during the first year is one of the most important factors determining fitness in birds. Birds have poor thermoregulatory abilities during the nestling period when the plumage is not fully developed, thus temperature during the nestling period is a serious candidate to affect post‐fledging survival, although it has been ...

Growth, fledging success and post-fledging survival of juvenile oystercatchers Haematopus ostralegus

open access: yes, 1995
We studied the consequences of differences in growth rate on the subsequent survival of Oystercatcher Haematopus ostralegus chicks. Fledging success increased sharply with growth rate, from zero in chicks growing at less than 6 g per day to about 85% in ...

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

open access: yesSymbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

Ontogeny of adaptive antibody response to a model antigen in captive altricial zebra finches. [PDF]

open access: yesPLoS ONE, 2012
Based on studies from the poultry literature, all birds are hypothesized to require at least 4 weeks to develop circulating mature B-cell lineages that express functionally different immunoglobulin specificities. However, many altricial passerines fledge

Supporting Pathways into College and Careers: The Case of Adult Education ESL in Community Colleges

open access: yesTESOL Quarterly, EarlyView.
Abstract Research has increasingly focused on the importance of college preparation and career and technical education (CTE) for multilingual learners (MLs), many of them classified as “English Learners,” in K‐12 schools. Less attention, however, has been paid to the collegiate and professional aspirations of another significant population of MLs in ...

Acoustic Mimicry of Begging Calls and Its Geographical Differentiation in Nestling Common Cuckoos Toward Oriental Reed Warblers 大杜鹃雏鸟对东方大苇莺乞食鸣叫声的声学模仿及其地理分化

open access: yesWildlife Letters, EarlyView.
Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...
