Although the bell has not yet rung to signal the end of the Cumberland
County Foray, here are some early returns.  From May 29 to June 2, data
were collected in all 75 blocks of Cumberland County--but I currently
have the field cards for only 69 of those blocks in hand.  The average
number of species recorded in the 69 blocks is 57.23, fairly close to
the 60 species total that was considered to signal complete coverage in
a block during the Tennessee Breeding Bird Atlas project (the foray
species totals were usually achieved in 2-3 hours of effort; I'm not
sure what the average number of hours of effort was in a block during
the atlas).  The range of species totals in the 69 blocks was 27-77.
The lower figure was achieved in the Roddy 1 block which has less than 1
mile of public roads and no other legal access; the higher figure was
achieved in the Isoline 2 block.
 

Night counting periods of 30 minutes were conducted in 22 of the blocks.
Confirmed breeding evidence in the county was recorded for at least 60
species, with some nice confirmations among them , including Bald Eagle
NY (nest with young).

 

House Wrens displayed a considerable increase in presence since the time
of the atlas (1986-1991) when that species was recorded in three blocks,
being recorded in over 20 blocks during this year's foray. Tree Swallows
displayed equally great increase.  No Swainson's Warblers were recorded
in a Cumberland County block during the BBA, but that species was found
in 4 blocks during this year's foray, all as a result of the intrepid
work of Barb Stedman.

 

Some disappointing misses included no Veeries on Dorton Knob or anywhere
else; no Rose-breasted Grosbeak there either, though one singing male
RBGR did turn up as a likely late migrant in a block to the northeast of
Crossville.

 

Ed LeGrand had a migrant Mississippi Kite during the foray, maybe the
best non-breeder to be located during the event.

 

All told, some evidence of breeding was found for 110 species, and 4
species were recorded as certain or probable migrants.

 

MANY thanks to the following for contributions to the foray and to
knowledge of the breeding birds of Cumberland County: John W. Barthelme
(2 blocks), Roseanna Denton (2 blocks), Michael J. Hawkins (6 blocks),
Edmund K. LeGrand (23 blocks), Joseph E. Mast (6 blocks), Barbara H.
Stedman (20 blocks), Steve Stedman (16 blocks), Winston A. Walden (4
blocks), Carol D. Williams (2 blocks).
