Hi All,

There was a definite upswing in nocturnal migration during the last week of
April. Small movements of birds were apparent on the Caribou and Portland,
Maine, weather radars on the nights of 24, 26, and 29 April. On 30 April
there was a strong migration at both sites. On that night, winds were very
light (<10 km/hr) over the Bay of Fundy and Gulf of Maine from surface to
1,500 meters so conditions were good for crossing from Maine/New Brunswick
to Nova Scotia. The records on eBird indicated significant increases
overnight of Yellow-rumped Warblers and Savannah Sparrows; and small
increases for Palm Warblers and Ruby-crowned Kinglets. The acoustic
monitoring station at Carleton, Yarmouth County, had the most night flight
calls of the season on the night of 30 April with 11 calls. There were a
total of 28 night flight calls for the week, a number that is not untypical
for April. The table below summaries the results of acoustic monitoring for
this week. Reports for the season can be found at:
http://www.johnfkearney.com/Carleton_YarmouthCounty_2016.html.
