This nest was installed by BHP and GF&P on May 2011 after the birds built a nest on a nearby power pole. The pair was unproductive the first year.
What to look for
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.
Pair arrived earlier than any other year. Male was seen on March 30th perching near the nest. Female arrives on March 31st on a beautiful spring day with heavy snow and cold temperatures in the forecast..
Snowed four inches on the 9/11. Birds have now today left for the winter. It was another successful year. Three eggs with two fledglings. The pair is now experienced and very well adapted to their nest environment.
First observation of the pair on the nest. Coincidentally, the arrival of the pair is on the same date as the previous two years. The male arrives a couple of days before and then early in the morning the female lands at the nest.
On the same day that the first egg was laid, two other pairs of Osprey circled the nest. The pair was quite agitated and in a few occasions there was mid-air contact. Thankfully, neither bird was injured and they were able to defend the nest.
With 42" of snow in April, the birds are having problems preparing the nest. With constant snow cover on their nest, they have resorted to starting a new nest on a nearby electrical pole. We're hoping that warmer weather will provide some relief.
One of the young Osprey took its first flight off the nest yesterday. The second one, shown in the picture, is testing its feathers by going aloft over the nest while his mother gives him encouragement. The mother was seen pushing him off the nest with her chest encouraging him to go. Also, upon returning from a flight she bumped into the chick with its talons. He, however, did not get the hint.
The osprey's first egg hatched this morning around 5:00 am. The male and female were seen looking towards the middle of the nest probably wondering about the fluff ball moving there. The male got a fish and as usual ate part of it in a nearby branch. However, the eating behavior was somewhat different. We noticed that he was eating very fast and ended up choking on a bone. After about a minute he was able to cough it clear (nerves?). He then brought the fish to the nest and the female took it and proceeded to feed the two hour old chick. Once the chick was fed, the female was unsure how to sit on the two remaining eggs. After a few tries, she decided to move the chick to the side under her wing. Very exciting stuff. The chick's name: DODE.
Towards the end of April the male continued bringing sticks to the nest, many times preferring to simply approach a tree and snap a branch while in flight. The pair would also collect pine needles in the same fashion. The needles and other soft material would provide the lining of the center of the nest.
