Ivo hatched and was ringed in 2013 by Joosep Tuvi, in a nest 50 km NNE in Jõgeva county

Iiris has no rings and so one can´t say something definite about her

- - - -

Nest is located in South Estonia, Tartumaa, not far from a fish farm. Natural river and ponds are in vicinity, too.

Ospreys (Pandion haliaetus) 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.

Checked a statistics about when the ospreys were last seen on the nest. Hopefully this year's very warm summer will make them linger a bit more..

For Irma:
in 2013 - she was last sighted on 23 August
in 2014 - 21 August
in 2015 - 19 August
in 2016 - 24 August
in 2017 - 20 August
in 2018 - 26 August
in 2019 - (Iiris)

So Irma might presumably start the migration any time from 19 to 24 August. (2018)

Chicks:
in 2013 Kaido last seen on 8 September, Kenno 12 September
in 2014 Elar and Aino were last seen on 12 September
in 2015 Yolanda last seen on 5 September, Niina on 15 September, Thor on 19 September
in 2016 Ivar last sen on 4 September
in 2017 Daimar was last seen on the nest on 27 August and Daisi on 11 September
in 2018 Kaja was last seen on the nest on 3 September, Heli and Jaak on 6 September
in 2019

So the young osprets can presumably migrate any time from ~ 27 August to 19 September (2018)

The male:
in 2013 Ilmar was last seen on 12 September
in 2014 Ilmar was last seen on 12 September
in 2015 Joosep (J3) last seen on 18 September
in 2016 Ivo last seen on 4 September
in 2017 Ivo last seen on 11 September
in 2018 Ivo last seen on 6 September
in 2019

So Ivo might presumably start his migration journey any time from ~ 4 September to 18 September
(2018)

Hello osprey fans :hi:

Many thanks to Urmas and friends for bringing this webcam back to life :loveshower:

Cam came online yesterday late evening and introduction for the topic is still in progress, I will work on it as my time allows.
But at least we have a place where we can post actual events.

There was a time when the cam was buffering, but now it seems to stream continously

Let´s hope for a happy season here and please stay friendly and tolerant to each other, a very important behaviour in these special times of our lives
:gathering:

Great to meet you all back here! :wave:
