18:40 PM
Raindrops block the view a few times, the weather is miserable and Iiris crouches in the nest, shakes her head to get rid of the moist. I'm always worried when the wind shakes the nest fierce, I'll never forget when former Irma left the nest years ago and the little brother of Ivar was blown off the nest.
I always wonder what happend to Ivar. Is he one of those Ospreys flying sometimes around the nest? Don't they remember the place where they were born?

:hi:

Thanks for all reports with and without pics :thumbs:
Those bark pieces are a splendid camouflage for the eggs in the nest - isn't the nature pedantic and logical! :nod:

19:45 Ivo brings fish with head!!! :laugh:
Iiris saw him coming and began to vocalize in her gentle voice and stood up. But Ivo flew past the nest, then turned around and gave the fish to Iiris. Surely he intended to eat the head but Iiris softly thanking made him change his mind. 8-)

20:53 a half of fish flies in with Ivo, happy Iiris takes off with it.

This afternoon Ivo has been particularly industrious and caring. :D

Sorry for breaking the time schedule with my posts. :blush:

:wave: Jenny,
Ivar was born in year 2016, so he probably has returned from the south in year 2019 for his first breeding season. If he was very lucky, he found a good nesting site, or even a free nest.
Even though he certainly remembers his birth area, he won't return it directly. He might return to the regions in proximity, though, and search for his own nest and mate. :rolleyes:

"Those slowly maturing birds do not begin a return migration until they are in their third calendar year - the second full spring of their lives - and they seem in no hurry to get north.
They depart wintering grounds a month or two later than adults do, and often travel at a slower pace. Once they reach breeding grounds, they begin the search for a nest or a site to build one in. Because these can be hard to find, young ospreys tend to wander, often considerable distances.

With luck, these wanderings bring them to a site they can claim, and they may even attract a mate once there. But more than likely they will fail at all of this and return in fall to their old wintering site, only to come back the following spring - earlier this time - and try again.

In regions with many Ospreys and few nest sites, it can take two or three years for these birds to find a nest and a mate - a luxury of delayed breeding that only a long - lived bird such an Osprey can get away with
.
"

"Good nests, and especially the sites to build them on, are in short supply, each nest a major investment in time and effort, so there is fierce competition for them. After losing a nest it may take an Osprey a year or two to find another."
(from Poole A.F., Ospreys, The revival of a global raptor).

A rare occurrence this season - fish with it's head on :laugh:

It is also a bit unusual how Iiris often carries it away - in her beak

Iiris is back, and she brings a tree bark with her

Good morning Sunshine,
thank you so much for your answer. Ivar is the Osprey in my picture here in looduskalender and he will always have a special place in my heart. Maybe one day we'll find out, on hand of his identifacation ring, where he is located. I know that this is fruitless searching, but I'll never give up hope.
Wish you a nice day

Iiris eyes looked scared, something must be in the air. Ivo came to the nest und was making sounds, probably to scare this intruder. Iiris is hiding under Ivo's plumage.

13:53:14 Iiris, a pole vaulter, approaching the nest with a long stick hanging in her claws.
Ivo watched her over his shoulder, she landed safely but lost the stick as expected. :laugh:

Seira, Sunshine :wave: and thank you for the pictures.

Lena, thank you for the pictures. :wave:

The same scenario with fish with head as yesterday was realized.

Iiris saw Ivo flying with a wonderful fish with head and started to vocalize not in so gentle voice as usual. 8-) Ivo's plan to sneak past her unnoticed and eat the head himself failed. :innocent: When Ivo landed on the nest, Iiris had some trouble to get the fish beacuse of the strong wind. Finally she flew happily away with it. :headroll:

Just a guess - a roach? :puzzled: Correct me who knows which one was it.
