Comparing timing and routes of migration based on ring encounters and randomization methods [PDF]
A method for comparing two migration routes is introduced. In the method are needed approximations of the average daily positions which are computed based on averages of dates and of positions in a window sliding through the encounters ordered in ...

Nest-site habitat partitioning by Arctic, Common, and Roseate terns
When closely related species that share aspects of their habitat niches nest in sympatry, selection is expected to favor species-specific differences in nest-site selection that allow birds to partition habitat. We tested habitat-partitioning theory in a
