Novel Nesting Behavior in Cave Swallows

The Wilson Bulletin, 2003
The Cave Swallow (Petrochelidon fulva), first discovered breeding in Texas in 1915, originally was thought to be confined to sinkholes in central and western Texas. During our survey of bridges in Brazos County, Texas, we discovered Cave Swallows modify and use old Barn Swallow (Hirundo rustica) nests, a previously unreported behavior.

A note on pterosaur nesting behavior

Historical Biology, 2007
Based on examination of eggshell structure and predicted vapor conductances in eggshells in recently described material from Argentina and China we conclude that pterosaurs buried their eggs. Egg-burying imposes theoretical restrictions on the distribution of pterosaurs, both geographically and spatially, raises the possibility of thermal sex ...

Nest platforms increase aggressive behavior in common loons

Naturwissenschaften, 2007
Artificial manipulations of habitat, such as those that incorporate adding nesting boxes or platforms for birds, often enhance the breeding success of threatened animals. However, such alterations are likely to have unintended behavioral and ecological effects that might negatively impact the target species or others in its community.

First Description of Nest and Nesting Behavior of the Nightingale Wren

The Wilson Bulletin, 2000
Nests and nesting behavior of the Nightingale Wren (Microcerculus marginatus) in Panama are described. Two nests were found at the ends of horizontal burrows in dirt banks, presumably excavated by other species. The nest chambers were lined with dead leaf fragments. Clutch sizes were two and three eggs. Incubation period was 19 or 20 days for one nest,

COMPARATIVE NESTING BEHAVIOR OF CRABRO MONTICOLA (HYMENOPTERA: SPHECIDAE)

Northeastern Naturalist, 2003
The nesting behavior of Crabro monticola was studied at seven localities in upstate New York and northwestern Pennsylvania over seven years. More than 100 nests were observed, excavated, measured, and drawn. Contents were removed from the cells, analyzed, weighed, and identified. All nests were excavated in sandy soil near woodland in late spring-early
