Snag/nest is almost due east from the Crocker Springs RV park along the Grizzley Creek road to Lake Davis. Nest visible from the RV park through slim sp[ace between conifers. Also, visible from second driveway on left north of park.
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.
04/21/19 Stopping for lunch, I observed this nest with just a head showing in the nest. This surprised me as the nest had not been added to for at least three seasons, so I did not expect the nest well to be so deep. The male arrived with a fish, and the female immediately left the nest leaving the male with this Huh? look.
This nest was pointed out to me this date by the owner of the small RV park. He said it has been there since the 2014 season, and occupied bith that year and 2015. While observing the nest from a long distance, one bird did fly into the nest. I will be able to tell more in better weather.
