Dear VA birding community,
There is a general sense among conservationists and the general public that
populations of Whip-poor-wills and Chuck'-will's Widows are drastically
declining. However, there has been no prior widespread or long-term
monitoring strategy to document these changes. Understanding the precise
magnitude and scale of population changes for these Nightjars are critical
if we are to plot a course for conservation.
The Center for Conservation Biology is initiating and coordinating the
Southeastern US Nightjar Survey Network to collect information on the
population distribution and trends of these two Nightjars. We have
organized a network of survey routes throughout ten southeastern US states
including, Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina,
South Carolina. Tennessee, Virginia, and West Virginia and have designed a
set of protocols for efficient data collection.
The success of this program relies on volunteer participation.
Nightjars surveys are standardized population counts conducted along
specific routes once a year at night. Each route consists of 10 stops along
a predetermined 9-mile route. At each stop, a volunteer counts the number
of Nightjars seen or heard for a six-minute period. Each survey route will
not take much more than 1 hour to complete.
Nightjar surveys must be conducted during a very specific set of dates for
data standardization. The survey window for this 2007 season is May 24th
through June 8th. These dates are chosen to coincide with the period of
brightest moonlight, and the greatest and most consistent Nightjar detection
probability. Calling rates of Whip-poor-will's and Chuck-will's Widows are
strongly influenced by moonlight. Surveying only on bright moonlit nights
will yield the most precise and accurate population estimates.
Please consider adopting a survey route in Virginia or a nearby state. We
have created maps of existing routes and methods for you to create your own
route that may make the survey more amenable.
If dates for the 2007 survey season are arriving too quickly for you, please
consider registering for a route for the 2008 season. Population trends can
only be determined if data from routes if collected annually. In fact, data
become more scientifically credible towards indicating a real trend each
year data is collected from the same route.
Contact Mike Wilson, mdwils@xxxxxx to adopt a route.
