Subject: nightjar survey network
<< In the spring of 2007, The Center for Conservation Biology
constructed the Nightjar Survey Network to begin the process of
collecting data on the population distribution and population trends
of Nightjars across broad regions of the United States. The Network
was initially introduced into the southeast and is being expanded in
2008 to provide coverage throughout the contiguous United States.
The support I have received from many state and federal agency
personnel in the Southeast has been great and very helpful. I cannot
thank you all enough.
I have added a brief report on findings from the initial year of
survey on the project website.
The Nightjar Survey Network relies on volunteer participation by
conservation-minded citizens, biologists, and other like-minded groups
to adopt and conduct survey routes. Surveys are conducted much like
the United States and Canada Breeding Bird Surveys except for
important modifications to accommodate the biology of Nightjars.
Nocturnal behaviors of Nightjars are strongly influenced by moonlight.
Activities such as calling and foraging increase under bright
moonlight and breeding may be directly tied to the lunar schedule.
The Nightjar Survey Network was designed to take advantage of this
life history trait by restricting surveys to bright moonlit nights.
This protocol substantially improves the accuracy and precision of
surveys by reducing the systematic errors associated with moonlight
and will further act to strengthen the statistical power needed to
draw conclusions from collected data.
The Nightjar Survey Network has both short-term and long-term
objectives that are considered spatially and temporally scalable. As
soon as a significant portion of the Network routes are annually
surveyed, they will begin to provide results of Nightjar population
status for local regions and for broader geographic areas.
Short-term objectives have 4-5 year time horizons and include:
1) Gaining a better understanding of the population distribution
of Nightjars across their breeding ranges.
2) Learning how the composition of different habitats in a
landscape influences Nightjar abundance.
3) Improving the performance of the survey design.
Long-term objectives have time horizons of 10 yrs or greater and include:
1) Determining the scale and magnitude of population changes.
2) Providing alarm signals at specific locations if Nightjars are
becoming imperiled.
I welcome any interest, comments, or suggestions, and any distribution
of the program by Southeast PIF members to the general public is
valuable. I have also created a 2-page flyer that contains much of
the info above as advertisement of the project. This is available for
download on the website.
Please fell free to email me and I hope you visit the network's
website if you haven't yet for more details:
