Wood Warbler and Common Rosefinch in Horten, Vestfold & Telemark, Norway during April & May 2020

Two species that are sort after by birders and bird photographers every year are Wood Warbler and Common Rosefinch. Both species are not common locally but are easily found in suitable habitat and more than often than not by their characteristic songs.

Wood Warbler / Bøksanger phylloscopus sibilartix
The usual breeding areas for Wood Warbler were checked from 29th April and several visits during May. Experience has shown that the first Wood Warblers often start to sing on the edges of breeding territories while leaves are not completely developed. However, several established pairs in my area move deeper into the woodland later in May and then only can any serious estimate number of pairs be made. On 20th May in my small project area there were 3 singing males of which at least 2 were paired and another calling bird located. So, a total of 6 birds present this year. Bird photographers often use playback to attract birds closer but this does not work well for this species and often results in singing males becoming stressed and moving around and often higher in the branches. Patiently waiting for singing birds to use their favourite singing perch will give far better photographic images.
The images below were taken without the use of playback.

Common Rosefinch / Rosenfink Carpodacus erythrinus
Locally the first singing male arrived on 16th May and by the 19th singing birds were recorded singing at three different localities at least. As with Wood Warbler, the use of playback will often result in birds moving around and even may be chased out of territory by a recording and not a real competitor. One well known locality normally has up to three singing males that compete for an unknown number of females and unnecessary competition from false-males may well ruin breeding success.
