|This graph shows the Maurice River Osprey Colony beginning in 1985 until present. It represents the restoration activities of Citizens United members in increasing the number of osprey in the watershed. It does not include the 25+ nests that we have built for the PSE&G estuary project, nor the 6 nests made for tributary creeks along Delaware River for the state Bureau of Emergency Management's Oil Spill Response Program boom pilings. Additionally, we have constructed nests for the N. J. Division of Fish and Wildlife, Endangered and Nongame Species Program to be used along the Atlantic Coast. The accompanying graph charts only the nests the organization manages. A number of nests have never been used so the "nests up" figure includes those that osprey have never taken an interest in, rather than a low productivity per nest. Quite the contrary, the Maurice River Colony has the highest productivity per active nest in the State, as high as 2.8. The state average is less than 1.5. We did not begin to count eggs until 1991. Eggs are counted to determine whether a nest failed altogether or whether eggs were laid and then the nest failed. Since 1991 we also recorded the banding results. In 1985, when we began this project, there were about six chicks raised on the Maurice. In the year 2000 we banded 47 chicks; our record year was 2002 with 60 banded chicks. We are hopeful that the number of osprey raised continues to increase and can be stabilized.
