Look for 2 adults on the nest. The adult pair will show pair bonding behaviors such as vocalizations, aerial sky dances, and the male feeding the female fish. You may see the pair copulating, which typically begins 14 days before laying eggs.
Females will lay 1 - 4 eggs at a rate of one egg every 1 - 2 days. After laying, incubation starts. Look for adults taking turns sitting low in the nest incubating eggs. The incubation period can last 35 - 43 days.
Chicks hatch ~39 days after incubation begins. Look for adults bringing food to the nest and making "head bows" into the center. Chicks typically can't be seen until they are 2 - 3 weeks old, so feeding behavior is the only way to know chicks are there.
Around 4 weeks after hatching, look for the heads of chicks to show over the rim of the nest, particularly when adults bring food to the nest. Other times they lie flat and are harder to see. Count the number of chicks in the nest before they learn to fly
Chicks begin flying around 7 - 8 weeks old, and are still fed by the adults. Count the number of chicks who have successfully fledged the nest and are observed flying.
Chick Last Observed
4 - 10 weeks after fledging, chicks begin leaving the nest area to migrate south, once they have learned to fly and feed themselves. Record the date that the last chick left the nest.
Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.
light breeze, sunny, 68 to 72 deg, both male and female were seen on the nest area ( Channel Marker tower) and are working on rebuilding the nest as nearly all of the Material was blown off this winter. both both look healthy.
Say one of the birds in the area for the first time this season, believe it was the male, the bird was fledged from the pole as I slowed to take a better look, no nest activity yet, weather was cool around 48 deg expecting a Nor Easter to blow in mid day on Teusday, starting to become overcast.
Mid 80's, breezy, 10% overcast, high visibility, Both birds, on the tower, it looked like the female was maintaining her plumage as the male war feeding at least on chick, I could not make out if it was more the that.
Mid 70's, breezy, 10% overcast, high visibility, Both birds, vocalizing with two other birds. Do not appear to be threatened by them they have been doing this for a couple days, during observation on bird from Nest #6084 broke away and returned to the nest.
Overcast, windy and warm, high visibility, both birds noted, female on purch on the rail, Male flying around the nest during the observation time the male glided in and mounted the females back, she was receptive, after a short time (30 to 40 Sec) he stretch his wings and glided off with little to no effort. and fly glided around the nesting area. she stayed on the roost
16:10- clear sky, low 60's, light breeze, single adult near nest (larger then the bird noted in nest) on a utility pole near nest eating, could not make out what it was eating. Bird was flushed by road traffic.
