Persistent Genomic Erosion in Whooping Cranes Despite Demographic Recovery. [PDF]

Mol Ecol
ABSTRACT Integrating in‐situ (wild) and ex‐situ (captive) conservation efforts can mitigate genetic diversity loss and help prevent extinction of endangered wild populations. The whooping crane (Grus americana) experienced severe population declines in the 18th century, culminating in a collapse to ~20 individuals by 1944.

A network of refugia: Whooping Crane drought response informs international habitat conservation goals

Conservation Science and Practice
Whooping Cranes land in a palustrine‐emergent wetland amid row crop agriculture near Atkinson, Nebraska, during spring migration in April of 2020 (photo by M. L. Forsberg). From 2023 to 2024, the U.S. and Canada updated conservation plans for the Whooping Crane through international workshops.

Diurnal time–activity budget and habitat use of Whooping Cranes (Grus americana) in the reintroduced Louisiana nonmigratory population

The Wilson Journal of Ornithology, 2023
Time–activity budget studies provide valuable insights for better understanding animal behavior relative to spatial and temporal habitat use. We examined a reintroduced, nonmigratory Whooping Crane (Grus americana) population to determine how time ...

Differential shortstopping behaviour in Whooping Cranes: Habitat or social learning?

Global Ecology and Conservation, 2023
Many migratory bird species have begun shifting their wintering grounds closer to their breeding grounds, shortening their yearly migration distance through a behavior called shortstopping.

Anatomical bases of sex- and size-related acoustic variation in herring gull alarm calls [PDF]

, 2014
The hypothesis that anatomical or physiological factors can constrain the production of vocalizations is supported by an increasing number of examples from a range of taxa, where acoustic variation is related to sex, body-size or condition. In this study,

Deciphering Cryptic Population Structure in Western Sandhill Crane Subspecies (<i>Antigone canadensis</i>) of the Pacific Flyway. [PDF]

Ecol Evol
Sandhill Crane populations of the Pacific Flyway are made up of breeding populations nesting west of the Rocky Mountains, and isolated by intermediate mountain ranges. Here, we analyze microsatellite markers, mitochondrial DNA sequences, and mitochondrial haplogroups to elucidate population genetic structure and found substantial genetic ...

Avian cerebellar floccular fossa size is not a proxy for flying ability in birds [PDF]

, 2013
Extinct animal behavior has often been inferred from qualitative assessments of relative brain region size in fossil endocranial casts. For instance, flight capability in pterosaurs and early birds has been inferred from the relative size of the ...

Differential changes in the onset of spring across US National Wildlife Refuges and North American migratory bird flyways. [PDF]

PLoS ONE, 2018
Warming temperatures associated with climate change can have indirect effects on migratory birds that rely on seasonally available food resources and habitats that vary across spatial and temporal scales.
