Last year, the streaming cam viewers of Loch Arkaig Osprey nest went from its norm of 60,000 viewers to over 400,000. People from around the world watched Louis and Aila raise three – Dottie (male), Vera (female), and Captain (male)- Ospreys to fledge. As the pandemic moves into its second year, each one of those viewers and more are holding their breath, biting their finger nails off, pulling their hair out, or pacing back and forth for the arrival of Aila. Louis has now been home from his winter migration to Africa for five days. He is working hard to get the nest ready for Aila’s arrival. But where is she?

Late this afternoon, there was a spotting of an unringed Osprey passing over Arran heading due North. Could it be Aila? Depending on how the Osprey flies it is 80-100 miles and if it is Aila, she should arrive tomorrow! It is going to be one sleepless night with devotees getting up early to fix their eyes on the screen! One woman said it very well, ‘They saved my life last year during the pandemic. I want Aila home safe!’

The Osprey nest on The Landings Golf course on Skidaway Island near Savannah, Georgia is expecting its second hatch soon. The first is getting around nicely after hatching on 13 April.

Just look at those beautiful baby blues. They will change to an orange-yellow and then when this little one is an adult, they will turn to that bright yellow distinctive iris of the Osprey.

Now are you going to be nice to your little sibling?

At the Lesser Spotted Eagle nest in Latvia, Andris is bringing nice presents of prey to Anna. They are both working hard on preparing the nest. Look at all that beautiful pine.

Also in Latvia, Milda took several breaks from incubation. She was looking around but I did not see Mr C trying to incubate eggs today (let me know if he did). She just might have given him the boot. There has sure been a lot of drama around and under this nest with White-tailed eagles fighting. Very disturbing for Milda who, sadly, is probably incubating unviable eggs.

At 7:14:44 pm Diane is calling to Jack to bring food to the Achieva Osprey Nest in Dunedin, Florida. Tiny Tot is asleep. Fish was delivered at 3:21:46 am and again at 11:55:01. Tiny Tot had a good feed on the early fish and had a good crop. He did not get any of the 11:55 fish despite being up close. If the weather forecast is correct, this nest can expect thunderstorms beginning around 4am Friday morning. It says 40%. I hope they are wrong. The temperature is cooling to 23 or 24 right now.

Tiny Tot is hungry and he is starting to call Jack, too. He’s there calling on the far left.

Now the two larger osplets are up and calling for dad, too. Unless this is a whopper – and I do mean a HUGE fish – Tiny Tot might not get any food tonight. He ate his fill this morning when the other two weren’t that interested – and yesterday, too.

And there it is. The third fish of the day, if you count the middle of the night delivery, lands at 7:59:14.

It looks like 2 mantled the fish and has it. You can see her in the middle. Tiny is to the far left keeping himself down. Dad quickly leaves. But thank goodness, Diane steps in and takes control of the food delivery! That is all Tiny Tot needs – the older stealing the fish! That fish is not that big.

Diane feeds 1. Tiny Tot is between Diane and 2 who is watching but not being aggressive.

At 8:05:09, 2 has walked around and behind 1. There was no attack on Tiny Tot. Meanwhile, Diane continues to feed 1. It is unclear if Tiny Tot is getting any bites of fish. There are no tell tale signs of his body moving slightly up and down but I cannot be certain, one way or the other.

And then 2 who is so aggressive to Tiny Tot just gets up and turns and goes the other way. By this time there is only half of the small fish left. Is it possible that Tiny Tot will get a little of this fish?

A few minutes later, 2 turns around behind Diane. The behaviour is quite odd because if food is involved, 2 is always threatening to Tiny Tot. Yesterday 2 was not hungry. I thought it was trying to pass a pellet or it was just the heat. This is perplexing.

And then 2 flaps its wings and goes towards the rim of the nest looking back.

Then 2 walks behind Tiny and raises its neck like it is checking on the fish.

But nothing. 2 turns around and goes to the rim of the nest. Meanwhile, less than half the fish is left and 1 is still eating. At 8:11:49, 1 walks across the nest and, once again, comes up behind Diane settling under her tail. How odd.

But just as quickly, 2 backs up and sort of looks off the rim of the nest, again.

At 8:16:05, 2 is back up by Diane and she feeds it a bite of food.

At 8:17 Diane is still feeding 1. 2 is behind under between her legs and Tiny Tot is at the rim at the far edge of the nest watching. He will move up closer to Diane and the feeding. But as the light dims it is very unclear whether or not there was any fish left for him. It looks like 1 might have eaten the entire delivery. Still, around 8:30 it appears a slight shift in angle and height and perhaps, just perhaps, Tiny got the last bites by the tail. Tiny had a crop at 12:04 from the big meal earlier and while it is preferable that he eat more food more often, he will be alright. What is strange about this entire feeding is the behaviour of 2. And that is why I have detailed it so closely. Is 2 struggling to cast a pellet? Or is something else wrong?

The Great Horned Owls have amazing plumage and they are starting to get the distinctive tufts of feathers for their ears. Here they are, Tiger and Lily, looking like they are standing and having a chat. Some will think that they are ‘so cute’ but these owls are deadly. In Europe, there are more incidents of GHOWs killing entire raptor families than I want to think about. We have seen them hurling Harriet and M15 off their Bald Eagle nest in Fort Myers, Florida or the much smaller Boo Book Owl in Australia knocking WBSE Lady and injuring her eye. They travel at night while the other birds are sleeping and they fly silently with the help of their soft rounded feathers. The increase in their numbers, the loss of habitat and stated another way, the loss of large trees for nests is causing problems. These two should be branching and fledgling shortly.

Over at the UC Berkeley campus, Grinnell is having a very difficult time trying to get Annie to get off the eggs. Hatch watch starts on Saturday and Annie is always reluctant not to be right there when it starts!

While the Peregrine Falcons are on the verge of hatching, fledge watches are also going on around the globe. In Taiwan, the Black Kites ‘Pudding’ and ‘Brulee’ were born on 3 and 5 March, respectively. They were banded on 2 April – Orange K2 and K3. The average amount of time for Black Kites from hatch to fledge is 42-50 days. Pudding is 44 days old and Brulee is 42 days old.

Both are getting their wings stronger by flapping and flapping. And look at that magnificent tail. The fledglings generally stay in the nest perfecting their flying and hunting skills for another 42-56 days until they are self-reliant. The parents supplement their food.

Once the nestlings are older, they will sleep with their head tucked on their back. It is not under their wing although their beak might be. Did you know that sleeping this way allows the bird to relax its neck?

Thank you so much for joining me today. Stay safe everyone!
