Hi All,
There was steady nocturnal migration this week. The weather continued as
cold and wet but light south or southwest winds were prevalent during most
nights of the week. In most years, the third week of May marks a time when
many species are anxious to get to their breeding territories. Thus, there
is often evidence that birds are more willing to cross the Gulf of Maine
rather than crossing further up the Bay of Fundy. For example, this week
there were several reports in the local social media of warblers appearing
on fishing boats off the coast of Yarmouth.
The risk birds take in crossing large bodies of water like the Gulf of
Maine, say from Portland, Maine, to Beaver River, was highlighted in a
scientific article published this week in the journal, Ecology. A study of
Tiger Sharks in the Gulf of Mexico found that 39% of the sharks had the
remains of migratory songbirds in their stomachs. These findings indicate
that sharks are scavenging large numbers of birds that fall to their death
due exhaustion and other factors during their journey.
The most common species of the week was Ovenbird with an estimated total of
18 individual birds. There was a good representation of other warblers
including Common Yellowthroat, Magnolia Warbler, Yellow Warbler, Blackpoll
Warbler, Northern Parula, Black-and-white Warbler, Blackburnian Warbler,
Chestnut-sided Warbler, Yellow-rumped Warbler, Black-throated Green Warbler,
Nashville Warbler, and Northern Waterthrush.
Sparrows included Savannah, Chipping, and White-throated. Shorebirds were
represented by the local Willets and Spotted Sandpipers, and a small flock
of migrating Sanderlings.
Reports for the entire spring migration can be found at my website
