Azores archipelago is located in the North Atlantic,
consequently observations of birds of both Palearctic and Nearctic origin are
not rare there. We evaluate the local occurrence of two allopatric snipe, the
common snipe Gallinago gallinagoand
Wilson’s snipe G. delicata. A hurdle
model for fortnightly snipe counts on São Miguel Island
suggests an arrival of foreign birds in October-November. Morphological
characteristics were used to identify both snipe species among birds shot
during hunting seasons on Pico and São Miguel Islands. The Nearctic Wilson’s
snipe is an annual winter visitor to the archipelago, representing from 8% of
the hunting bags on Pico up to 56% on São Miguel.
Further studies, using emerging technologies, may shed light on the origin of
the migratory birds and their interaction with the local common snipe breeders.
