Fat Stores and Antioxidant Capacity Affect Stopover Decisions in Three of Four Species of Migratory Passerines With Different Migration Strategies: An Experimental Approach
- Environmental ScienceFrontiers in Ecology and Evolution
During migratory stopovers, birds must make decisions about when and where to travel and these decisions are likely contingent on their fuel stores, food availability, and antioxidant capacity as…
Golden Eagle dietary shifts following wildfire and shrub loss have negative consequences for nestling survivorship
- Environmental ScienceOrnithological Applications
ABSTRACT Wildfires and invasive species have caused widespread changes in western North America's shrub-steppe landscapes. The bottom–up consequences of degraded shrublands on predator ecology and…
Seasonal and Interspecific Variation in Frugivory by a Mixed Resident-Migrant Overwintering Songbird Community
- Environmental ScienceDiversity
It is indicated that fruits and seeds constitute substantial sources of sustenance for non-breeding songbirds, there is considerable separation of resource use among species in the fall and winter, and fecal estimates of contributions to songbird tissues should be interpreted cautiously.
Extraordinarily rapid proliferation of cultured muscle satellite cells from migratory birds
- BiologyBiology Letters
The results indicate that the rapid proliferation of satellite cells is not associated with total migration distance but may be related to flight bout duration and interact with lifespan.
Foraging ecology drives social information reliance in an avian eavesdropping community
- Environmental ScienceEcology and evolution
It is determined that foraging ecology best predicted playback response, with aerial foragers responding less often, and this findings align well with known links between the exceptional visual acuity and other phenotypic traits of flycatchers that allow them to rely more heavily on personal rather than social information while foraging.
