Bird Migrations and Nesting

Cooling Towers as Obstacles in Bird Migrations

Migrations of Green Turtles (Chelonia mydas) between Nesting and Foraging Grounds across the Coral Sea

Marine megafauna tend to migrate vast distances, often crossing national borders and pose a significant challenge to managers. This challenge is particularly acute in the Pacific, which contains numerous small island nations and thousands of kilometers of continental margins. The green sea turtle, Chelonia mydas, is one such megafauna that is endangered in Pacific waters due to the overexploita...

Bird Feeding and Irruptions of Northern Finches: Are Migrations Short-Stopped?

The provision of seed at feeders improves the survivorship of birds, facilitates range expansions, and influences habitat choice. In this paper, I examine the notion that bird feeding in northern parts of North America can short-stop the irruptive migrations of fringillids. Indirect data to support an increase in bird feeding over the past 25 years are provided. Using an area bounded by the App...

The relationship between childhood adversity and food insecurity: 'It's like a bird nesting in your head'.

OBJECTIVE Adverse childhood experiences, including abuse, neglect and household instability, affect lifelong health and economic potential. The present study investigates how adverse childhood experiences are associated with food insecurity by exploring caregivers' perceptions of the impact of their childhood adversity on educational attainment, employment and mental health. DESIGN Semi-struc...

Individual quality and age affect responses to an energetic constraint in a cavity-nesting bird

Individual variation in life-history trade-offs can be caused by differences in quality and age. We tested for individual variation in parental investment in incubating tree swallows (Tacyhcineta bicolor) subjected to a feather-clipping manipulation. Individual quality influenced how females were affected by feather clipping; lower quality clipped females showed a greater reduction in incubatio...
