Chicks of cavity-nesting birds do not ‘exercise’ prior to fledging [PDF]
Royal Society Open ScienceFledging represents a key life-history transition involving a rapid increase in workload associated with a rapid transition from sedentary nestling to volant, active fledgling.

Earlier hatching date rather than chick phenotypic quality enhances first-year survival in the black-headed gull [PDF]
Frontiers in ZoologyBackground Favourable conditions experienced during early ontogeny are expected to positively influence individual performance at later stages of the life cycle and determine lifetime fitness.

Genomic Integrity in Gull Chicks Predicts Colony Departure and Postfledging Movements [PDF]
Ecology and EvolutionIn species with parental care, the transition from dependence to independence is a critical stage during which juveniles must make key decisions for their future life.

Moonlight diminishes seabird attraction to artificial light
Conservation Science and Practice, 2023 Rescue programs aiming to mitigate light‐induced mortality of seabird fledglings have reported that fewer birds are grounded (and rescued) during full moon nights. Two non‐mutually exclusive hypotheses have been proposed as explanations: (1) reduction of

Efficacy of some pesticide alternatives on the desert locust Schistocerca gregaria (Forskal) under laboratory and field conditions [PDF]
SVU-International Journal of Agricultural Sciences, 2019 The efficacy of chlorantraniliprole (Coragen®), spinosad (Tracer®) and fipronil (Coatch®) was tested under laboratory conditions against the 5th nymphal instars and adult stages of the Desert Locust Schistocerca gregaria (Forskal), using various ...

An extreme type of brood overlapping in wild-living birds
The European Zoological Journal, 2022 Brood overlapping is a breeding strategy that aims at shortening the time between successive broods. Most typically, each brood is raised in separate nest and parents share care between broods.

Conservation Science and Practice, 2023 Seabirds are at risk of decline from multiple threats, including artificial light resulting in their grounding (“fallout”). Without evidence, it can be assumed that seabirds travel short distances from natal colonies to their fallout location ...

Diel patterns of predation and fledging at nests of four species of grassland songbirds
Ecology and Evolution, 2021 Although it is common for nestlings to exhibit a strong bias for fledging in the morning, the mechanisms underlying this behavior are not well understood. Avoiding predation risk has been proposed as a likely mechanism by a number of researchers. We used

A path forward in the investigation of seabird strandings attributed to light attraction
Conservation Science and Practice, 2023 A variety of anthropogenic threats cause mortality and population declines of procellariiform seabirds. Globally, fledglings of many colonial procellariiforms become stranded in towns and cities during their first flights from the nest, which occur at ...
