We are requesting Henslowâ??s Sparrow field observations in Tennessee and
Kentucky.
Last year we initiated a highly successful Henslowâ??s Sparrow Atlas project
in Tennessee
and Kentucky. We are again requesting local birders to collect information
specifically
about Henslowâ??s Sparrow populations and habitat use throughout the states
Tennessee
and Kentucky.
If you are interested in participating in this important conservation project,
you can download data forms and a full explanation of the protocol (PDF files)
atâ?¦
http://web.utk.edu/~jgiocomo/HESPatlas.htm
The website provides a link to the data form and field protocol, and a longer
version of the protocol including pictures of Henslowâ??s Sparrows from
Tennessee and Kentucky, and possible habitats. The basic information we are
requesting includes the exact location, the number of birds (Henslowâ??s
Sparrows and other grassland birds), and pictures of the habitat.
As you may know, according to the Breeding Bird Survey (BBS) Henslowâ??s
Sparrow
populations have been declining range-wide at a rate of 8.7% per year since
1966, one of the most severe declines of any bird in North America. But you
may not be aware that trend is based on detections of Henslowâ??s Sparrows at
just 174 BBS observations over the last 25 years among hundreds of survey
locations in the thousands of square miles in the Henslowâ??s Sparrow breeding
range.
More information is urgently needed to target management efforts to reverse
the severe population declines. The Henslowâ??s Sparrow Atlas Project is
designed to determine the population status and habitat and area requirements
of the Henslowâ??s Sparrow and other grassland associated species. A recent
meeting of Henslowâ??s Sparrow â??expertsâ?? sponsored by the USFWS has
identified a
Henslowâ??s Sparrow (and grassland bird) atlas as a top priority to advance
national level conservation efforts.
In 2006 in Tennessee, Henslowâ??s Sparrows were located in five new counties
and the total
know populations now includes over 300 pairs in the state! These new
observations offer hope that other populations could be found throughout the
state if there are enough people looking in the â??rightâ?? habitats.
Our hope is this atlas project will provide birders the excuse to spend some
time birding between May 15 and July 15 in habitats that are usually not
popular birding areas, namely unmowed agricultural grasslands, leading to the
discovery of other unknown Henslowâ??s Sparrow populations. Areas in West
Tennessee are especially likely to have new Henslowâ??s Sparrow population
discoveries, but they have been discovered in East TN.
Thanks for your cooperation!
