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.
first nest with verified 3 nestlings. mom busy feeding. #1 is full and has back to mom; #2 is being fed; #3 is waiting patiently next to #2. didn't watch long enough to see any beak bonking, hopefully i didn't miss it
oh, no, another 3-chick nest. such a hard, hot, dry, summer for this many babies, but apparently they are hanging in there so far. this nest has had one tragedy after another, praying hard for success this year.
one osprey guarding the nest. RED-TAILED HAWK UPDATE: FLEDGE for at least one, because i found him frozen in a nearby tree, with a male bullock's oriole swooping at him from above - the fledgling didn't move a muscle. i didn't see any other fledgling around the nest, which is definitely empty now.
the pair is on the nest platform, i'm guessing staking their claim, but no chicks this year. RED-TAILED HAWK NEST UPDATE: nest is still hanging in there, we have at least one chick w/mom or two chicks in nest, couldn't tell for sure (pix)
no osprey, no activity. REDTAIL HAWK NEST UPDATE: bad storm blew apart many nests on monday, some redtailed hawk chicks rescued from blow-down nest about 3 miles from this one, all chicks accounted for but the nest tree has clearly suffered some damage and the nest is now more exposed. fingers crossed they will fledge successfully
no osprey in sight, very little work's been done on the nest (she said with a sigh of relief) RED TAIL HAWK NEST UPDATE: observed at least 2 white chicks in the nest today, very peaceful setting in which to grow up.
no one in nest. finally had a chance to talk to georgia. she said the pair has been mating and bringing in sticks, but so far no eggs. i'm hoping they spend the summer bonding and fixing up the nest, getting so late for babies...
well whatdayaknow - the lone osprey has been joined by a female, who appears to be down in the nest, incubating? it must be this nest's pair, and they waited out the goose somewhere. glad to see the nest occupied, hope it has better luck than last year, but it's getting late :-(
well, i was wrong, this nest isn't empty, there's a mother goose hunkered down in it. it is a deep nest, so she could have been here for awhile and i just didn't see her. no sign of any upset osprey around, though
talked to georgia today (257-5081). there were 2 chicks in this nest all along. a severe hailstorm hit the 1st week of august, hail was size of golf balls, damaged their roof, trailer camper, snapped trees, etc. georgia advised that the day after the storm, one chick was gone. the other chick moved around in the nest, but it never flapped its wings and seemed to have difficulty getting to mom for fish. about 5 days ago it also died. that hump i saw in the nest is the dead chick. mom was seen flying around the nest for the first few days after her 2nd chick died, but georgia hasn't seen her in the last couple days. it's time for the magpies and vultures to do their job. georgia advised that these parents raised two chicks successfully last year, so at least there's that. i'm guessing the 1st chick was blown out of the nest and predated. i wonder about the 2nd chick possibly being caught up in fishing line or baling twine, but the fact that his difficulty in the nest seemed to start immediately following the storm means maybe it was the hail that injured him. very sad update.
this nest is definitely empty. i've seen no action in or around it in 3 days. i'm hoping that my hatch date is off and this chick has fledged; will continue to watch it in hopes i see it back in the nest getting fed. can't really count it as a fledgling at this point, can i?
either the chick was laying very low in the nest or it's fledged. no parent around, thought i could see a bit of a hump in the nest, but it never moved, so i might have been staring at a pile of sticks. seems a bit early for this one to fledge, though...
watched mom preening on side of the nest for almost five minutes, about to give up and move on when a fairly big bobblehead popped up!! based on my vast experience, i'm guessing this chick is at least 6-7 days old. only saw one, but at least now this isn't a failed nest!
well i arrived early enough in the morning to see mom finishing up a fish in the nest. if there are chicks, they already got fed and were down for a nap, because once again i did not see any bobbleheads.
well for pete's sake, the one nest i thought was all settled is not. saw female and 2 male flying around nest, then female landed in nest while one male continued to chase the other for the entire time i watched (about 5 minutes). i'm guessing no eggs yet!
