Revtangen BO August 24th

Still ESE and warm, but too windy in the middle part of the day for any efficient trapping. Nets open 05.30-14.30, netmeter hours approx. 3000. Playback on garden warbler, reed warbler and grasshopper warbler through the night and early morning, tree pipit later on. 

Ringed: Sparrowhawk 1, tree pipit 3, european robin 1, redstart 4, redwing 1, reed warbler 2, garden warbler 9, willow warbler 22, pied flycatcher 4, spotted flycatcher 1. Total = 48. 

Willow warbler is by far the most numerous passerine ringed at Revtangen BO, and this one ringed today was willow warbler number 20.000 for Revtangen BO! Løvsanger nr. 20.000 på Revtangen OS.

Observations: Kestrel 1, sparrowhawk 3, temminck's stint 1, yellow wagtail 1, grasshopper warbler 1. 

This kestrel frequented the trapping area today, using the net poles as hunting posts. It already had a ring with a number probably starting with the letter "S", so very likely a bird from Finland. It even flew into a mistnet and escaped....frustrating. Denne tårnfalken, tilsynelatende merket i Finland, unnslapp nettmaskene i dag. Frustrerende.....
