Tjeldstø 17 April 2018 - Lunchbreak

Light cloud with southerly winds.

I have been travelling a lot the last few days and today I had to work from home. A short lunch break at Tjeldtsø provided some interest with a neck-ringed Greylag grågås ringed near Karstø last summer. Rather early for a young bird from Tjeldstø to have moved south so early - but who knows when the first chicks hatch late April / early May and by late June Greylag numbers are dropping in Øygarden....

It is always cool to see colour ringed birds but yet again this project has yet to be registered on http://www.cr-birding.org/

After some detective work it seems that http://www.geese.org/ is the place to report such sightings.

From the life history of this bird...

This Heron gråhegre caught several stikkleacks stingsild whilst I watched.
Evidence that fish-eating birds can actually benefit game fisheries (there are trout ørret in this lake).
Hunters and fishermen often want to get rid of birds like Herons and Cormorants but time and again it is proved that they eat species that prey either eat the eggs of more desirable species and / or are in competition for food with Trout etc. 

Newborn lambs - lots more than a few days ago and very obviously a lot more imminent - judging by the size of many of the sheep....

Other species included Redshank rødstilk, a few White-tailed Eagles havørn, Wheatears steinskvett and so on.
