typical USFWS survey period. We also searched for nests adjacent to the survey
routes. To limit disturbance to nesting females, we used forward-looking infrared radar (FLIR) cameras, rather than pointing dogs, or trapping and following
radio-collared hens. Over the three survey routes, one showed a peak display of
March 24; the second, March 28; and the third, May 7. This proves there is much
variability between sites with as-yet-unknown factors involved in timing. Using
the FLIR camera, we located 28 nests and four broods. Peak nest initiation was
April 10, which was a week following the peak found by Liscinsky. With a small
sample size, this difference may be insignificant. What is interesting, however,
was that the peak of nest initiation occurred prior to the USFWS survey window.
We feel that this might be indicative of when resident woodcock display at peak
density, which also is the time period the USFWS seeks to target. Finally, the
FLIR cameras proved to be highly effective and efficient, and caused little to no
disturbance of nesting hens. Given the success and low impact on woodcock, this
method seems preferable to the use of pointing dogs or trapping and telemetry
for locating and monitoring woodcock nests. The FLIR also was successful in
locating other species and nests.

Does Spring Gobbler Season Start Too Late? Our season is timed to open when,
on average, a majority of hens are incubating. It's the Saturday closest to May 1.
Incubating hens are less likely to be disturbed by hunters, to abandon their nests
or be harvested accidentally. For hunters, the timing also maintains the satisfaction of hearing gobbling toms because gobbling intensifies when most hens are
busy incubating their eggs. Because the season's timing is based on a long-term
average, plenty of springs are on record when hens weren't yet incubating.
This can occur after harsh winters or when natural food supplies are
low. By the time the season opens, plenty of hens might have lost their
first nest to predation, and they are starting over. Our gobbler opening
date was established in 1968. Because of earlier spring green-ups and
the potential for more variation in spring weather from climate change,
during our 2010-14 hen turkey study, we determined nest incubation and the opening of spring turkey hunting should continue to
coincide. We compared the median date of nest incubation of 254
satellite-transmittered hens to the results of a study we conducted
from 1953 to 1963 of 6,119 brood sightings and back-dated to
estimated nest incubation dates. Median dates differed by only
two days; May 2 in the present study and May 4 in the previous
study. However, nest incubation timing varied greatly among
years and individual hens. Through four of the five years of our
study, the spring season opened three to eight days prior to median date
of incubation. So our annual opener continues to ballpark with the longterm median date of incubation initiation. Our course remains true.
