During the past few weeks, we have enjoyed watching the migrating passerines that pause to rest and refuel on Petit Manan. On the mainland, many migrants are spread far and wide throughout expansive forest habitat, often bouncing around high in the trees. However, here on PMI we have the rare opportunity to see songbirds up-close in the intertidal. Flies buzzing among the rockweed provide a perfect meal for these hungry birds. Since Petit Manan covers 16 acres and has only one tree (a twisted spruce that is a few feet tall), migrants are easily visible and concentrated within a small area. It seems almost surreal to find Blackburnian Warblers like this one hopping along the rocks, since this species normally feeds high in the treetops.

Many of these migrants have traveled all the way from wintering grounds in Mexico, Central America, and northern South America. It is amazing to think that such tiny birds can travel this far, and continue even further northward to breed. Passerines often travel by night to avoid predation, and we sometimes hear them calling after dark as they resume their journeys.
We look forward to having more migrant visitors, and adding to our quickly growing bird list!
