Description

This appears to be a first year nest located straddled across the cross arms of a power pole that also has two transformers attached. The power pole is directly below the dam creating Weber Reservoir, and only a few feet north of the Walker River as it leaves the reservoir. This is on the Walker River Paiute Reservation.

What to look for

Adult Arrival

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.

Incubation Initiation

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.

Clutch Hatching

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.

Nestling Count

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

Fledgling Count

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.

Nest Failure

Look for signs of nest failure like adult abandonment, adults no longer incubating eggs or feeding young.

04/25/22 Female on nest incubating, turning eggs. Male did not show in the 2.5 hours I observed.

06/27/21 The Paiute Tribe closed the reservation for all of 2020 due to Covid-19, so I could not monitor the nest. They did open the reservation just this June 25, so off I went about 100 miles southeast of Reno, Nevada this morning. When I arrived, the female was in the nest, and there were obvious young also. It took awhile to get things sorted out as the young were moving about as was the adult. I was finally able to discern there were three chicks, which is what they reared two years ago. Wasn't ;long before the temp hit 100 degrees.

03/27/20 Access to this nest has been closed by the Paiute Tribe due to COVID-19. Will check later should restrictions be lifted.

008/03/19 A friend birding the area told me about this nest on Friday, 08/02/19. This appears to be a first year nest, and no nest had been reported at this location before. When I arrived this morning (a 100 mile trip one way) the female was busy feed ing three chicks, and the male was perched on a nearby power pole. This is a popular fishing site, and two men wee very close to the nest but the birds did not appear to care. I parked on the dam itself, giving an almost level view of the nest. My guess is that the chicks will leave the nest in about two weeks, so will count the three as this season's success.
