inaccessable to observations using the bucket truck, therefore it wasn't 

 until July 1 that an accurate count could be made of the 3 young In this 

 nest. The young from all nests had fledged by the end of July except 

 for 1 individual In the Quarry Nest that didn't fledge until the second 

 week of August. By mid September all the birds had left the Millstone 

 site, marking the end of the 1983 breeding season. 



During 1983, Millstone sites produced the highest number of 

 fledglings since observations began in 1969. Two active nests produced 

 three young each, raising the average annual production rate to 

 2.4/nest. Even though the two new platforms remained inactive, a pair of 

 osprey did build a nest atop channel marker //4 outside the Niantic 

 River, 1 km away from the Bay Point nest. This nest failed, presumably 

 due to the boating activity. 



This year in Connecticut, osprey produced 40 young in 34 active 

 nests, slightly above last years annual production of 1.1/nest (Greg 

 Chasko, Franklin Hill Wildlife Area, Personal Communication). This is 

 the highest number of fledgings produced since the decline in the 

 1950-60 period (Table 1).
