Annual Massachusetts Census 
For purposes of getting comparative data, counts were made outside 
the Quabbin reservation as well as counting the singing grounds on 
Prescott peninsula. The great majority of the birds on the 80 singing 
grounds on Prescott were trapped and banded. Most of the birds recorded 
were heard several evenings over a period of about three weeks. The re- 
sults showed no significant change in the population during the last 
year. The totals were: . 
1950 1951 
129 131 
These included 23 birds tabulated by R. Norris in the Newburyport 
area in Essex County where many counts were made. 
Trapping and Banding Success 
Ten juveniles were banded from | broods found with a dog. 
One hundred and fifty-four individual birds were captured. These 
ineluded 3 birds banded in 1919 and 15 birds banded in the spring of 
1950. Only two of these were females. One hundred and thirty-four new 
adult males were banded. 
Including all repeats of this year 183 captures were made. 
Accurate records on 100 birds captured gave a trap success figure 
of 31 percent based on 31) trap-nights. Sixty-three sites where birds 
were captured in April on Prescott peninsula were retrapped late in May. 
Since traps. were left a maximum of two nights, and there was no time to 
ascertain if birds still were using sites, these results are not included 
in the calculations on success. 
There was a minimum of 20 trap failures. In 2h instances traps 
were sprung by rain, wind or animals. . 
Of 157 sites trapped by Unit personnel, 128 birds were captured.
