The preference of birds for new nestboxes may influence long-term monitoring results when nestboxes become older and when old nestboxes are replaced with new ones. This important limitation has not been emphasised in review papers on the inadequacies of nestboxes in studies of hole-nesting birds...
The blue jay is often referred to as the thief of the bird world. They are known for stealing nests and even preying on the smaller, defenseless birds residing in those nests. Despite this, blue jays are beloved by bird watchers for their iconic bright blue feathering and their wide range...
This pattern in attendance reflects a latitudinal contrast in parental care strategy, where lowland tropical birds reduce visits to the nest by increasing onand off‐bout lengths while maintaining the same proportion of time spent incubating their eggs (constancy). Similar constancy across latitude ...

Types of Finches Pine Grosbeak The Pine Grosbeak (Pinicola enucleator) is generally found in the coniferous forests all throughout Alaska, Canada, United States, New England, Siberia, Germany and North America. Durbec des sapins is the French name of these birds. ...
Begging brings benefits and costs for nestling birds: it can indicate their needs to their parents, but it can also be a cue used by predators to find the nest. The costs, like many variables related to nest predation, can be specific to what kinds of predators are present and their audi...
We measured nesting success of the American Robin (Turdus migratorius) in woodlands embedded within eight organic farms in eastern Nebraska. We modeled daily nest survival rate to identify land use and land cover patterns that optimize conservation of birds in organic farm systems. The percentage of...
For hole-nesting passerines, one of the most vulnerable phases is the breeding season, when the parents are bound to the nest (Ricklefs, 1969; Martin, 1995). In altricial species, the nestlings are entirely dependent on their parents for provision and protection; thus, when exposed to a ...
These birds are also placed in a subfamily ofAnthyinae, and are considered to be the close relative of dabbling ducks. These species are endemic to the Northern Hemisphere. Diving duck is primarily found in thefresh water. Unlike other species, these types of ducks can certainly fly. ...
The different habitat types could be easily identified as vegetation composition of the region was relatively simple. Photographs were taken as a record during the intensive surveys between April and November in 2007. Considering the requirements of birds, lizards and small mammals, all habitat types...
