Day 22

June 17. Day 22 for the chick! As many have noted, there are noticeable growth changes over the course of a day during this high growth-rate period. The absolute fastest rate is approximately between days 30 to 35, but the pace now is close to that. The wings will continue to elongate and get a little awkward as strength catches up. So far, there’s been plenty of fish to fuel that growth!

The chick watched dad move a stick then gave it a try. Last year’s trio all moved sticks regularly, and original dad’s only occasionally. It will be interesting to see if that’s an actual trend as years go on or just a coincidence.

Day 21: Netting carried off!

Sunday, June 16. The chick is 3 weeks old today and seems to grow moment to moment! They seem strong, curious, and unhesitant to urge mom to call for fish.

UPDATE: Dad accidentally carried off the netting! (This is why jumping to quick intervention is often not the ideal choice.)
Bird netting has been in the nest for a day now, but so far, it hasn’t caused a problem. It’s stiff nature makes it less of an entanglement hazard than a more flexible netting like fish net, thankfully. That doesn’t mean it isn’t a hazard, just less of one. The chick has been on top of it multiple times without entangling, so that’s somewhat encouraging. With luck mom or dad will hook it and carry it off accidentally.

Boulder County has a non-intervention policy, but they have been notified as a heads up. We’ve had many potential dangerous items in the nest, and they are typically resolved by the ospreys. With this being a human-made item, should it cause a true entanglement issue, any action or non-action decision will be made by wildlife biologists.

Day 19: Growing so fast!

Friday, June 14. The chick is 19 days old today and seems strong and healthy. Mom spent most of the night on the rails rather than over the chick since the chick can now thermoregulate and doesn’t need that protection. Body contour pinfeathers are prevalent now, but food resources are still primarily going into muscle and bone development for the next couple of weeks. From now through about day 35, they grow very fast, with the fastest pace from about day 30 through 35. After that, male chicks’ growth tends to taper off while females continue to grow for a bit longer.

Chick and stick!

Snapping Turtle vs. White Pelican

June 11. A snapping turtle and pelican got into a serious battle as the turtle tried to take the pelican down (and very nearly succeeded). The pelican sustained serious injury to its lower mandible an pouch, and after the altercation,  swam laps around the pond for about a half hour before taking off.  Boulder County authorities were notified.

A quiet day with one visitor causing only minor disturbance. The mama goose pulled reeds for her nest, leaving her eggs uncovered, for about a half hour. Good day!

April Fool’s Day with no foolishness!

The day was partly cloudy to overcast with a period of gusty wind in the late afternoon, turning to rain and lightning in the evening.  Though dad spent some time tangled in plastic yesterday evening and part of the night, he eventually freed himself, leaving the plastic in an unknown location. The plastic is progressively being buried in the center of the nest, and all baling twine has been carried off the nest (accidentally). 

Mom and dad reunited on March 24.  The first egg could arrive anytime from April 3 (ten days) onward, though more likely after April 8.

Mom, the Trash Collector

Every year, mom brings in plastic, baling twine, and other non-natural materials. In her eyes, these are the perfect nest-building additions.

The resident male only brings in natural materials, and accidentally carried off both plastic and twine from the nest today. The original resident male was as much of a trash connoisseur as mom, and the nest was consistently more littered than now!

 Here are some of the items in the nest today.

Site Relaunch with the 2024 Season

After sparse updates for the past few years for a variety of reasons, it’s time to revive the site for the 2024 season.

Some pages and info may be out of date. Updates will be made as time permits, but the focus will be on current info and nest activities.

Return Dates:

  • Resident Male: March 21, 2024
  • Resident Female: March 24, 2024

Residents returned March 28, 2023

Both mom and her new mate (since 2021) returned to the nest on March 28. A pair of geese had taken up residence, including laying 5-6 eggs, but the ospreys had no trouble reclaiming their nest.

Thus far, they’ve been carrying on business as usual, and after three tragic years, we’re hoping for low drama season with healthy hatches and fledglings.

Residents have returned for 2022!

Residents have returned!

Mom returned on the afternoon of March 27, and the male returned on the morning of March 28, 2022.

And they are baffled by baffle! Geese had laid claim to the nest and a rebar and streamer goose deterrent was placed by Boulder County on March 24. It worked! The geese could not defend the nest from the center, and Mom fairly easily displaced them after her arrival.

 

Boulder County removed the goose deterrent in the early afternoon
