Revtangen BO September 4th

Very light SE to no wind at all in the early morning, sunny and then gradually more cloudy. Increasing wind from SE-SSE, from around 11 trapping was inefficient because of wind. Playback through the night on Garden Warbler, Reed Warbler, Grasshopper Warbler and Aquatic Warbler. Later in the morning on Grey Wagtail, Tree Pipit, Meadow Pipit and Eurasian Nuthatch. 

Ringed: Sparrowhawk 1 (1cy female, first this season), Great Spotted Woodpecker 2, Meadow Pipit 23, Tree Pipit 2, "Greenland" Wheatear 1, European Robin 1, Grasshopper Warbler 3, BLYTH'S REED WARBLER 1, Garden Warbler 10, Blackcap 6, Common Whitethroat 3, Willow Warbler 5, Goldcrest 1, Spotted Flycatcher 1, Great Tit 1. Total = 61. 

Blyth's Reed Warbler 1cy. Notice plain tertials, short primary projection and short p2. Busksanger 1K.


Ringmerket: Spurvehauk 1 (første i 2017), flaggspett 2, heipiplerke 23, trepiplerke 2, "Grønlands"steinskvett 1, rødstrupe 1, gresshoppesanger 3, BUSKSANGER 1, hagesanger 10, munk 6, tornsanger 3, løvsanger 5, fuglekonge 1, gråfluesnapper 1, kjøttmeis 1. Total = 61. 

Grasshopper Warblers (1cy). Aged by fresh plumage. The under-tail coverts on one of the birds was slightly atypical, with the dark smudge centered around the feather shaft in a manner similar to Lanceolated Warbler, but in the latter species the streaks are thinner and doesn't reach the base of the feathers like they do on this Grasshopper Warbler. The pictures show two different individuals.
Gresshoppesanger 1K. 

Observations: The increasing SE brought a few raptors, including adult female Marsh Harrier, 1cy Hen Harrier, 5-7 Sparrowhawks, 2 Common Kestrels and a Peregrine. Apart from that little of notice apart from a couple of Grey Wagtails and a Nuthatch.
