Migratory connectivity in the Loggerhead Shrike (Lanius ludovicianus).

ABSTRACT:

Aim

We combine genetic and stable isotope data to quantify migration patterns in Loggerhead Shrike (Lanius ludovicianus), a species of conservation concern in North America, to assess how connectivity differs and impacts population evolution, ecology, and conservation.

Location

We sampled shrikes across the majority of their nonbreeding range, from the Atlantic Coast to the western United States east of the Rocky Mountains and throughout Mexico.

Methods

Our study used a Bayesian framework using δ²H_f from a breeding season origin feather and nuclear genetic microsatellite markers to distinguish between co-occurring migratory and nonmigratory individuals on the wintering grounds and, for migrants, to assign individuals to a breeding ground o
