Dear Crane Friends!

The migration of the cranes with transmitters  “Aivar“ and “Hauka 3“  who set out early has advanced again.

“Aivar“ again made a long migration leap and late in the evening on September 19 reached the Hortobágy National Park in East Hungary, the same area where he made a long stop last autumn. But then he arrived there almost a month later, on October 10.  Evidently he will stay there for some time now too.

The weather for the weekend promised to be changeable but that cannot stop the autumn migration that proceeds at full speed. Millions of birds have already passed us and millions are still on their way to here. The time has arrived when mornings in the garden are again full of  birds and exciting!

The sun rises at about 6.45 now and that is the moment to pick up the binoculars, a hot drink and paper and pencil and settle comfortably in a garden chair. During the next couple of hours you will see and hear some twenty bird species without much bother and maybe even such that you have not met yet this year.

Who is busy in the hazel grove and how?

Hazel nuts



Common hazel    Harilik sarapuu       Corylus avellana

The bell-shaped and soft husk that encloses hazel nuts is green, velvety and fringed at the edges in summer. There may be up to five one-seeded nuts in a group. By now they are nicely brown. The average diameter of hazelnuts is a couple of centimetres and the weight of a thousand nuts may be estimated at a kilo – or one nut, one gram.

When the kernel or seed (”nut”) cannot be easily loosened from the husk it may almost certainly be predicted that there is no kernel because the nut weevil has laid its eggs in the young seed.

Nest life has finished

Greater spotted eagle    Suur-konnakotkas        Clanga clanga


Tõnnipoeg is three and a half months old and rarely visits the nest if at  all. The nest life period has come to an end.

The parents raised Tõnnipoeg and taught the necessary knowledge for eagle life. Mother Tiiu should set out on migration in the second half of September. Father Tõnn stays to keep an eye on Tõnnipoeg and we can still meet them a month after Tiiu’s migration. With favourable weather they start the migration earlier.
