The number of intruders or interlopers – or floaters – causing tense interactions at or near nests is becoming increasingly more alarming. We have seen Grinnell at Cal Falcons chase a female intruder from The Campanile only to be killed. Both Alden and Annie have, since, had to defend their territory with one male interloper coming right into the scrape while eggs were being incubated!
When did we realize that the life of our feathered friends is not just fluttering around and singing at sunrise and dusk? It is becoming quite worrisome.
Rosie was incubating eggs at the SF Bay Osprey nest at the Richmond Shipping yard when an intruder arrived. Richmond does not seem to be around and well, just have a look. The adults that have eggs and chicks that depend on them need to be hunting for food not defending nests in situations that might injure or harm them fatally.
It is happening everywhere and events such as these are causing a lot of anxiety. This morning an intruder with a fish tried to land on the Llyn Clywedog nest with a fish after Seren had laid her third egg. Dylan chased it off! Is it my imagination or is it worse this year than last?
There is a real lack of suitable nesting sites. Ospreys have adapted well to various human made objects such as the Whirley Crane in SF or the light stand at the University of Florida in Gainesville. I just learned the other day that there is an Osprey nest on top of one of the light stands at the University of Manitoba. I had no idea. Ospreys will use human made platforms – what they require is that the sky be wide open so they have a 360 view of any predators arriving. Otherwise Ospreys like the tops of dead trees. Bald Eagles like trees but trees – good old sturdy trees – are in decline. Ron and Rita took to the Papadam nest that Ron Magill constructed and, as I have mentioned a couple of times, David Hancock of Hancock Wildlife in British Columbia is construction eagle nests with sun shades! In San Francisco there is a real desire to have some of that prime real estate that The Campanile provides. Good trees and good territories with a growing number of birds looking for them tends to cause much distress.
It is a joy to see these two eaglets after the very rough start at the Dale Hollow nest. Both hatched on the 28th of February. If we count hatch day, they are 51 days old now. More growing, more wingersizing, and more jumping to do before fledging. Thankfully we will be enjoying them for awhile longer.
An adult brought in a small fish. Little Middle stayed back watching. Little Middle has not forgotten that he needs to be cautious. They have had days of many fish and then not much. Hunger could bring out the cranky side of Big. This is typical of eagle nests where the parents tend to show the older eaglets that sometimes it is feast or famine in the wild.
Little Middle moves up to eat before the fish is all gone, thankfully.
Cornell Bird Lab has posted a possible pip watch for Big Red and Arthur. They say they are in uncharted territory with four eggs. We will all be learning something. We will all be anxious to check on the status of this Red-tail Hawk nest first thing!
Wednesday morning. Cornell called a definite pip. Bit breezy there at times today.
You can see the pip in the third egg from the left as Arthur rolls the eggs this morning.
Big Red and Arthur are going to be really, really busy by the weekend.
B15 is 97 days old today. Pa Berry and Missy continue to come to the nest and to bring fish. Sometimes B15 self-feeds and sometimes she wants Mum to feed her. She tried both approaches Tuesday afternoon. It is such a joy that she is staying around the nest – getting strong, figuring out how to live on her own one day.
Well, the first fish of the morning did not arrive until 11:11:14 and it caused tension on the UFlorida Osprey nest at Gainesville.
Each of the chicks was hot and hungry and had been anticipating a nice piece of fish much earlier. As a result the eldest was cranky and Little Bit didn’t help itself by pecking at Big!
As you might well imagine a hot hungry bigger sibling wasn’t too happy and Big turned around and pecked Little Bit until he went into submission. Little Bit needs to not be so cheeky.
What was interesting to me was that, after a couple of minutes, the Mum got tired of the nonsense of the fighting and moved the fish and all three got in line and ate. Well done Mum!
Little Bit went and did a ps at 11:34 and went back to join the line. He has a bit of a crop forming and there is still fish left. Behave Little Bit!
There is a new study that is out in The Guardian this morning warning that protected areas aren’t always protecting the wildlife they should.
A quick check of what is happening in some of the nests.
Idris and Telyn have their second egg at the Dyfi Nest in Wales as of yesterday, the 19th.
Dylan and Seren 5F have three eggs at their nest at Llyn Clywedog as of today.
The Foulshaw Moss nest of White YW and Blue 35 also have three eggs as of yesterday.
Everyone had a chance to eat fish at the Captiva Nest. Mum Lena is feeding Middle (Little) while Little (Mini) has his own fish on the left.
The two osplets are watching a Crow fly over head. Aren’t they just so beautiful? Look at those amber eyes and that plumage. Gorgeous. Did I say I love Ospreys?
The three eaglets on the West End nest of Thunder and Akecheta are still on the nest. Oh, these kids make me nervous.
Just look at the size of the eaglet standing by Thunder being fed. My goodness. Check out the size of those legs. Wow.
It is certainly a gorgeous morning with that deep cobalt blue water and golden glow filtering on the Two Harbours nest of Chase and Cholyn and their little one.
Voting closes today for the two eaglets of Liberty and Guardian. Be sure to fill in the form and get it in by 5pm Pacific time today! The link to submit a name is below the image.
At the Northeast Florida nest of Samson and Gabby, both of their eaglets have now fledged. Congratulations Rocket!
There will be an on line Q & A about the Cal Falcons on 22 April – that is Friday at 2pm Berkeley time. You can set a reminder!
Betyanka and Bukachek have their first egg at the White Stork nest in Mlade Buky The Czech Republic.
Thank you so much for joining me. There are so many nests with things happening that it is hard to keep up. Take care. See you soon!
Thank you to the following for their streaming cam where I took my screen captures: Capi Mlade Buky White Storks, Cornell Bird Labs, DHEC, Cumbria Wildlife Trust, Dyfi Osprey Project, Redding Eagles, CarnyxWild, Captiva Ospreys and Window for Wildlife, Explore.org, UFlorida-Gainesville Ospreys, and Berry College Eagles.
