Platform is very close to the road right next to a farm field
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.
final entry on this nest this year unless something unusual happens. i'm convinced this nest platform is nothing but a resting perch for the neighborhood ospreys. i don't understand why it's not being used; it's no closer to the road than many others and actually in a quieter location. maybe just a tad too far from the river?
nobody home today. i find this platform very interesting - it hasn't been used in 3 years, but i don't know why. it isn't any closer to the road than my goose nest or flathead lake sign nest (in fact, the road it's on is much less busy), but for some reason, no one wants to call it home.
goose mom left the nest with her goslings on 4/27/12, the next day a pair of osprey was busy fixing up what I THINK was their nest last year. this happened with joan and wally's osprey pair last year - goose in nest, osprey m/d waited 2 weeks for goose to leave (after failing to drive it out), then the day mama goose and babies left, osprey m/d returned to the platform and used it that season. i'm hoping this nest has been abandoned for the osprey platform down the road...which i guess i have to now add...
spartanmt: well what do i know about osprey housing standards? today i saw an osprey pair back in this nest. i have no idea if it's the same pair i saw a week ago or not. i didn't see any activity between these two sightings but will keep watching to see if someone sets up house here.
have not seen either osprey back on this nest since last week, which is a good thing. males in 3 new platform nests today, probably after turning down nest #957. will keep watching until things calm down...
4/13/12: finally, the flathead lake ospreys have come home! both male and female seen in this nest at same time, but they left shortly afterwards. i'm hoping they moved onto fennon way platform, as this nest is full of baling twine - not good!!
