Description

This nest is on a platform in the center of a field just south of the Colt State Park Offices ("the Barn"). It was erected in 2023 in an attempt to move an existing pair that had nested on the chimneys of the park offices. The platform sits on a carbon fiber piling.

May 1 Dgb 2 N N
Note: Small nest rebuilt Mating activity observed
May 2 Jim O 2 N N
Note: Initially pair on nest, both standing. One flew to tree nearby. Then the other flew to a different tree. Nest is quite sparse.
May 6 Dgb 1 N N
Note: Female in nest makes occasional flights Another bird (male?) in tree about 75m distant entire period of observation
May 12 Jim O 1 N N
Note: Initially one adult female standing in nest. It quickly flew to a tree at the edge of the field and remained there. In viewing the nest through a scope I noticed feathers and bones hanging from the east side of the platform. I took photos. Later as I was packing up to leave a passerby told me something had just fallen from the nest. I walked over and took photos. I think it is likely the remains of a dead osprey. The carcass was picked clean with just a few feathers and bones left. I reported it to the staff at the park office. The nest was substantially larger than when I checked it last week.
May 19 Jim O 1 Y N incubation
Note: Female in nest incubating. No other Osprey in the area. I'm presuming her mate died last week. If she successfully hatches her eggs she'll have a hard time protecting them and hunting for fish to feed them.
May 25 Dgb 2 U N incubation
Note: Initially 2 birds at nest. One departed early in observation. Head of second remained visible over edge of nest
May 26 Jim O 2 U N incubation
Note: I was surprised to find M and F at the nest, having thought the male was killed previously. F was low in the nest incubating. M was initially standing on the edge of the nest calling repeatedly, then flew to a nearly tree at the edge of the field.
May 30 Dgb 2 U N incubation
Note: Female visible in nest. Male arrives at 11.48 carrying a fish then departs. A number of smaller birds approach nest during observation with some perching on branches extending from nest
June 2 Jim O 2 U N incubation
Note: M in nest incubating. F returned wet but without a fish and stood briefly in nest calling to ward off another Osprey flying in the area. Then F flew off again leaving M to incubate.
June 9 Jim O 2 U N incubation
Note: Pair present. Male incubating. Female standing in nest and calling. F flew off and perched in a tree at the edge of the field. M calling. A 3rd Osprey cruised by low over the edge of the field eliciting calls from the platform but it left quickly.
June 12 Kristin&John 1 Y N incubation
Note: Observed 1 bird low in nest, incubating.
June 13 Dgb 1 U N incubation
Note: Male on nest

June 21 Kristin&John 1 Y N incubation
Note: Observed 1 bird low in nest, incubating.
June 23 Jim O 1 N N
Note: Female standing in nest, calling, very agitated. There is a red-tailed hawk in the woods calling (not visible to me). Female flew toward the hawk several times and eventually I saw it fly off. Four other adults flew low over the area. Also a Turkey Vulture. No sign of incubation or sighting of nestlings, but sometimes stood holding wings partially out to provide shade which could indicate young.
June 29 Dgb 2 N N
Note: Female on nest, male returned to nest at 6.00 female began vocalizing and continued until male left at 6.03
June 30 Jim O 1 N N
Note: 1 adult sitting up in nest. No indication of eggs or nestlings.

Note: Adult female with 3 juveniles in nest. One juvenile eating unassisted while the other two called for their share. One got in and took the fish while the third continued to call. Three other Osprey flying in the area provoked defensive calls and crouching.
