Caspian Tern at Lake Musconetcong
(Click on the photo for a larger image)
The first tern of 2015 in the mocosocoBirds region was found today by Mike Ostrow: a Caspian Tern in the southern section of Lake Musconetcong. It was present late this afternoon as other birders viewed it from Koclas Drive. Other species of interest at the lake today are 2 Red-necked Grebes and 2 Red-breasted Mergansers.
Red-necked Grebes and Loons at Boonton Reservoir
2 Red-necked Grebes continue at Boonton Reservoir. They are often viewed from the north end of the reservoir giving that classic distant Boonton look. 22 Common Loons continue as well as 4 or 5 Horned Grebes. A group of 4 Bonaparte’s Gulls was flying back and forth at the north end this morning. Pine Siskins were in the trees by the walkway. These Siskins are probably the same as those wintering in the neighboring cemetery. A Common Raven flew over the walkway.
Two Bald Eagles are regularly seen at the top of the island. One is an adult type; the other is an immature seen in the photo below. The 125+ Double-crested Cormorants and approximately 40 Great Blue Herons nesting on the island do not seem disturbed by the eagles’ presence.
An interesting development on the island of the reservoir the past two years is the consistent sighting of Great Egrets. 8 Great Egrets were scattered near the ground in the trees at the base of the island this morning.
175 Common Mergansers remain. Seeing them breast-stroke in unison rather than fly when fleeing an area is a sight to enjoy.
2 Red-throated Loons and another group of 7 Bonaparte’s Gulls were seen after dawn at the north end of the reservoir (Simon Lane). The Red-throated Loons were not seen the remainder of the day.
