[nysbirds-l] Sit-and-Wait (Good) vs. Active Foraging (Bad) Strategies

2010-11-05 Thread Shaibal Mitra
I spent a little over an hour at Captree this afternoon, during which the 
Common Ground-Dove was seen just once, and for just a few minutes.

About a dozen birders were searching for the bird, and it became quite clear to 
me that their mostly uncoordinated efforts were not likely to produce favorable 
outcomes.

My conclusions are as follows:

1. Newly arriving searchers should discreetly approach someone already present, 
exchange cell numbers, and make an effort to fit into a coordinated strategy. 
If the first person you approach turns out to be a misanthrope, find a more 
civic-minded birder--there will be many there tomorrow.

2. It is best to wait quietly and motionless, preferably in a car, while 
scanning an area where the bird has been seen in the past. This bird likes to 
forage in short grass, along the margins of taller, denser vegetation. All of 
the margins the bird has favored are relatively narrow, so birders walking or 
standing in a prime spot are not likely to see the bird in that spot.

3. During periods when the bird is not being seen, it is grossly 
counter-productive for multiple birders to walk and drive repeatedly along all 
of the preferred margins.

4. All of the best margins can be surveilled from as few as six fixed points, 
four of which can be worked from a vehicle parked at a discreet distance from 
the margins in question:

   a. a point near the northeastern corner of the east lot, giving vantages of 
the north edge and the eastern foot-path toward the fishing piers.
   b. a point near the northwestern corner of the east lot, giving vantages of 
the north edge and the western foot-path toward the fishing piers.
   c. the extreme southwestern corner of the main lot, giving vantages of the 
western half of the driveway to the boat launch area.
   d. a point giving vantages of the eastern half of the driveway to the boat 
launch area, and some of the roadside margins east of the toll booths.
   e. a point near the eastern end of the south lot, giving vantages of the 
driveway to the south lot.
   f. a point near the exit of the west (boat launch) lot (where it exits back 
onto the Ocean Parkway), giving vantages of the roadside margins west of the 
toll booths.

5. When news of the bird's presence is circulated, people moving over in hopes 
of seeing it should take great care to avoid approaching by a track that might 
disturb the bird. Pay close attention to cues from people already on the bird, 
and, if in doubt, call one of them for a suggested route.
