Greater spotted eagle (Clanga clanga, earlier Aquila clanga)

Greater Spotted Eagles are large migratory raptors that live across Europe, the Middle East, Asia, and parts of Africa.They occupy lowland forest and forest edges near wet areas, including meadows, bogs, and marshes, along with river-valley woodland.
They are complete long-distance migrants, they winter in the Middle East, Southern Europe, Central and Southern Africa. The migration to Africa and back takes place mainly via the Bosporus Strait, the Middle East and the Nile Valley.
The greater spotted eagle arrives in Estonia at the end of March and leave in September, but individual birds can still be sighted in October.
Population is classified as vulnerable to extinction The suspected population numbers fewer than 10,000 mature individuals 2500–6600 pairs. There are appreciably 10 – 20 pairs in Estonia but half of them probably mixed pairs with LSE
The primary threats are habit degradation and habitat loss, human disturbance and
hybridization between GSE and Lesser Spotted Eagle (Clanga pomarina )
Description
Length: 59–71cm
Wingspan: 157–179cm (another source 130-180)
Tail: 23–27 cm
Weight : male 1.7-1.9 kg , female 1.8-2.5 kg up to 3.2kg
Colour: very similar in general to its closest relative the lesser spotted eagle, which shares part of its range. Adult has dark brown with slightly paler flight feathers. Underwing-coverts generally darker than flight feathers. Bands of white spots across upper-wing of juveniles.

Diet and Hunting:
Greater Spotted Eagles eat frogs, snakes and lizards, waterfowl, fish, insects, carrion, and small mammals up to the size of hares.
They hunt in flight, from a perch, or on the ground. They also steal food from other raptors, including other Greater Spotted Eagles
Nesting
GSE usually construct their nests themselves and inhabit them repeatedly on subsequent years, especially if not disturbed. Occasionally they use the old nests of other larger birds of prey (the common buzzard, the northern goshawk) or of the black stork.
Lays 1–3 eggs in a tree nest. As a rule, only one eaglet survives because of cainism.

TÕNN

Tõnn hatched in the year 2008 on the nest in western Estonia
He has transmitter and the white ring with code 7X

TIIU has no ring

Tõnn started to breed either in 2015 or rather in 2016 and was successful

In 2017 cam was installed on the nest but Tõnn and his mate went to other nest. Breeding was successful with one fledged eaglet.

In 2018 cam was installed on the current nest and we watched their life.

Nice
Same nest as last year.
Seems like the transmission is not the best and the clock is dragging.
Heard song trush and coal tit singing and skylarks passing anyway

March 29

Good morning

thanks for the new thread season 2020

8:31 a pigeon visit

8:35 a second pigeon came into the nest. The one who arrived first nodded her head constantly. The other jumped around her and hopped on her head too. Suddenly the first pigeon got up and pecked the other. the flew away.

Thank you, Liz , so interesting behavior , it's the first time we see wood pigeons couple in the cam nests

Wood pigeons again at 14:07

WOW, thank you Crissy , so interesting ritual dance, the third one was superfluous

Hello to all!
Accepted again to be in the "native" nest!



I hope that our couple will arrive very soon and this season will be successful!

12:33 A woodpecker

13:36 - 13:37 A busy nuthatch, 13:41 ...again

14:52 A nuthatch

I think it was the beginning of eagle calls 14:02 and 14:34
There are jays here too but don't think they have that deep voice.

Well Tõnn is a smart guy and probably have watched the webcam and seen the snow on the nest and waits for it to melt

Hellem! Thanks for the time stamp. Yes, these sounds are reminiscent of the GSE alarm.
