June is thé time of the year to catch all the young birds who just flew out. For us, this means we catch a lot of tits, chiffchaffs and other (young) birds. Last week, we had CES 6, and that was not spectacular at all.. we trapped 23 birds. That is not much for the last week of may. Often, between the end of May and beginning of July we catch most birds during the project. Last time, the youngsters weren't eager enough to fly into our nets, so they decided to stay out (perhaps not all birds had flown out). So I decided that today should be the day that we would trap all the youngsters. Until 9.30 this wasn't the case at all, the number of birds caught so far laid around 15 orso. Not much.
When I went round at 10 I came across 6 Great tits and 2 Blue tits hanging in the nets! Finally a group of tits! The rounds after, produced about 15 Great tits and 6 Blue tits, which meant our daily total would be raised quite a bit!
Some other young birds caught today: Blackcaps (Zwartkop), Chiffchaffs (Tjiftjaf), Nuthatch (Boomklever), Short-toed treecreeper (Boomkruipre), Blackbird (Merel)
Adult birds caught: Several Marsh Warblers (Bosrietzanger), Reed warblers (Kleine Karekiet), Reed bunting (Rietgors) , House Sparrow (Huismus), Garden Warbler (Tuinfluiter), Blackcap, Chiffchaff, Song Thrush (Zanglijster).

Yesterday I checked out the website of the Portland bill Bird Observatory . On the website I saw that they'd recently trapped both Marsh and Reed Warbler. I saw the photos of both birds on which one could clearly distinguish the larger upperbill of the Marsh Warbler. Therefore, I put my focus today on photgraphing the bill of the Marsh Warblers. And indeed, one can clearly see that the upperbill is thickker an the bill from a Reed Warbler. It is a good sub-identification mark for Marsh Warbler. Furthermore I photographed the back of the two Marsh Warblers because of the light tips on the fringes of the primaries and secondaries. Also a identification mark for Marsh Warbler.
I also took an overall shot of one of the Marsh Warblers

Total amount of birds trapped today: 60 birds
Unfortunately I will spend the rest of the weekend studying for my exams coming week...
