Estonian Osprey Nest (Mai & Mati) 2017

[Bea]

We are looking forward to the sixth season observing this nest and its inhabitants!

Introduction on LK main page in English: http://www.looduskalender.ee/n/en/node/1230

The resident couple in 2016 were Mai (ringed, 29, on left ankle, metal ring on right ankle) and Mati (metal ring right ankle).
Three eggs were laid, after second chick had hatched, one of the two chicks vanished overnight, reason unknown.
Third chick hatched, so two chicks were raised on the nest.
They were named Neeme (CN) and Paavo (CP), with DNA result it turned out that both were male.

Mai (29) and Mati in 2016


Nest is located in South Estonia, Võrumaa.
A military base is close, so it is not unusal to hear motor sounds from trucks and other vehicles, sometimes even shots.

A fish farm, as well as a river, is not far, so good hunting conditions for Ospreys.

Ospreys reach body heights of 50-66 cm, and wingspans of 1,27 - 1,74 m. Females are bigger than males.

- Winglength ♂ 448 bis 495 mm ♀ 470 bis 518 mm
- Weight ♂ 1,12 bis 1,74 kg ♀ 1,21 bis 2,05 kg

Usually two or three eggs are laid and incubated 36-41 days.
Young Ospreys fledge after 50-54 days.

While Looduskalender was offline (EENet had maintenance work) our Osprey cam came online! Thank you!

Just right in time to see a wonderful sunset ....


Nest looks still untouched, so we probably missed nothing meanwhile

12 April
7:48am and 7:52am
Osprey calling out and a fly-by over the camera.

[lianaliesma]

8.05 May be Mati

[lispet]

9:29 An osprey comes and goes. Did not see legs.


9:36 metal ring, right leg

[lianaliesma]

9.35 Seems to me it is Mati with a metal ring on the right leg. Brought nest material

[lispet]

Head marks

[Rujasu]

I don't know how unique each osprey's plumage is or if it even stays relatively similar through the years, but the shape of the white patch above the peak would suggest it is indeed Mati. There's a brown patch that comes down roughly in the center of it, maybe a bit to the left, and a smaller brown "spike" closer to the right eye.

2016 screencap for comparison:

[Malewitsch]

Banded male Mati?

[Kizo]

14:03 An osprey come to the nest and left immediately.


15:11 He brought the material back.

[Cessie]

14:22

It is so good to see Mati!!!
He is busy fixing up the nest!
Earlier this morning he landed twice on the nest, but he wasn't facing the camera!
Also he was busy calling out and chasing away something that we couldn't see.

[Birdfriend]

I think it is Mati, yeah, the great nest builder is back.

Busy Mati is continuous working on the nest, hopefully Mai or an other female comes soon.

[Birdfriend]

I made this pic from afternoon. Mati was at the nest for some minutes, he looked around as if he search for Mai. I have sorrows about her suddenly disappearance in last year.
