Hi Keith and all,
I have found that for birds that have multi-syllabic flight calls such as
Greater Yellowlegs or Solitary Sandpiper, it is more accurate to count all
the single notes and then try to estimate the number of birds. In the case,
of the 57 Solitary Sandpiper calls, I estimated that these represented 6
birds. Last year I had Solitary Sandpipers on 8 nights from July 23 to
September 29.

Interesting as always. One thing I see in this data that has me puzzled is
the 57 Solitary Sandpiper in July at the Carleton site but no reports from
either site in the first week of August. But we see more of them in the
field in Aug and Sep than we do in July. Presumably more will be picked up
in the weeks to come.

Subject: [NatureNS] Nocturnal migration monitoring for the 1st Week of
August
Hi All,
I have posted reports to my website on the acoustic monitoring of nocturnal
migration during the first week of August at two sites:
-The Carleton, Yarmouth County, station:
http://johnfkearney.com/Carleton_Yarmouth_County_2017.html
-A new station at Cape Forchu, Yarmouth County:
http://johnfkearney.com/Cape_Forchu_Yarmouth_County_2017.html
In summary, warbler migration was considerably greater at the inland station
at Carleton compared to the coastal station at Cape Forchu. There was
evidence of tern and shorebird migration at the Cape Forchu station. No rare
birds were detected at either station.
