And there were moments, proud moments, in their lives, when they were clever enough to snatch a small bird at roost
off his perch.
Now, though the said chicken was then at roost
in the stable, and required the several ceremonies of catching, killing, and picking, before it was brought to the gridiron, my landlady would nevertheless have undertaken to do all within the time; but the guest, being unfortunately admitted behind the scenes, must have been witness to the fourberie ; the poor woman was therefore obliged to confess that she had none in the house; "but, madam," said she, "I can get any kind of mutton in an instant from the butcher's."
Gray bats were listed as endangered under the Endangered Species Act in 1976, primarily due to population declines caused bv disturbance at roost
From the beginning, they used low-disturbance methods to perform research at roost
Remaining at roost
sites for short durations limits guano accumulation beneath roosts, making it difficult to detect whether structures are being used as night roosts.
All other characteristics were similar at roost
sites and random sites (Table 1).
The cluster actually can serve as a unit for heat production and cause an increase in temperature at roost
sites in caves (Twente, 1955; Betts, 1997).
For data collection at roost
structures, each roost tree was treated as a plot center and a circular plot was surveyed at each roost site.
The lower numbers of cut stumps at roost
sites was likely because many roosts were located in unharvested greenbelts surrounded by partially harvested stands, and random plots for these roosts frequently were located in harvested portions of the stand where stumps were abundant.
At three of the roosts our counts decreased an average of 1.0 per year in roost 2 (3, 5, 2, 0, 0, 0), 1.5 at roost
58 (6, 4, 2, 2, 0, 0) and 7.0 in roost 178 ('72, 61, 46, 43, 36, 37) but, because of low numbers of bats, only the last of these was significant (df 5, chi square 20.8).
Predicted body fat of juvenile bats at roosts
in interior Alaska (= 1.47, s = 0.53 g) was also greater than values reported for juveniles of this species at the Vermont swarming site (= 0.57, s = 0.06 g) and the New Hampshire maternity roost (= 0.67, s = 0.14 g) (Kunz and others 1998).
We will work closely with local governments to improve council practices, but councils will continue to have authority to manage flying-foxes at roosts
in urban areas.
