It was second spring with lockdown and no international travel. However, the spring 2021 has been really busy for us leading weekend trips for estonians as well as carrying out different field surveys.  Although I did missed guiding, I cant say it was a boring spring. Below you can see some of the highlight moments I was fortunate to witness during this spring.

It was really hard to miss the Eurasian Pygmy Owl this season. Brief field work effort in early March produced sightings of 5 pairs at Leidissoo NR in a single weekend.  Eurasian Pygmy Owl, March 2021, photo by Tarvo Valker.

First but not last Wolf sighting of the spring. I managed to see Wolf three times at two different locations being my best Wolf season so far. Photo taken by my client Piret Rabakukk. 

In April I was busy with looking for Lesser White-fronted Goose.  I found single Swedish re-introduction bird and also spent two days with Fennoscandian main flock (75 birds this spring) on Hiiumaa island.

The best self-found bird in April was a Red Kite. Although clearly spreading, the species is still uncommon in Estonia. It was only my 3rd self-found Red Kite in Estonia and also county tick.

In early May I had short 5 day family-birding holiday on Hiiumaa island.  Fabulous birding and spectacular visible migration to witness. Highlights being success twitch of the Estonian 2nd Rock Thrush, while self founds included White-billed Diver, Pallid Harrier, Hoopoe and Ringed Ouzel.
