Hibernating Amsterdam parakeets
Ring-necked parakeets Psittacula krameri visiting a potential nesting cavity today, in a wall in Amsterdam Oost. Reportedly, it were Great spotted woodpeckers Dendrocopos major that constructed the cavity first, but it was later taken over by the parakeets. Whether any of these bred there this year remains unknown. For Amsterdam there are only two other reports of Ring-necked’s occupying holes in walls (here the species nests in tree cavities), but breeding did not get confirmed. This one fits at least three parakeets. Perhaps they find some warmth together this way; it’s currently cold as **** here and much too early for breeding. (Thanks Frank!)

Schiermonnikoog (August 20 - 23)
All work and no play makes Jack a dull boy (and all play and no work made Jack a mere toy..?), so I was off to Schiermonnikoog, a small island located in the Dutch Waddensea, for an educational as well as recreational bird ringing experience at the "Groene Glop", our bed & breakfast & ringing station (with Joop vA (and family) and Jorien vS).
At times it was crowded at the coffee table. Captures can be found on http://www.trektellen.nl
Bycatch: a Great Green Bush-Cricket Tettigonia viridissima

Two-egg clutch of Barn Owls (Tyto alba guttata) in a wall mounted nest box located in a green suburb of Zwolle, The Netherlands. An infrared camera connection showed that one of the two breeding birds disappeared during early egg-stage (halfway April), but the true cause of failure remains unknown. The box was installed over 20 years ago and became occupied by a single Barn Owl pretty much every winter and occasionally in summer. During summer 2015 a second bird appeared and a first breeding attempt was made the following year, which also failed during early egg stage. Today the box got cleaned out, the eggs were removed and 85 pellets were collected and will be used to identify prey items.

Ring Ouzel (Turdus torquatus). April 20, Zwolle (The Netherlands)
A relatively rare (and primarily spring) migrant in this part of the world. Found at a doorstep after a probable window collision. Third CY female (??-http://www.ringouzel.info/infoandadvice/Ring%20Ouzel%20Photo%20ID_Birdwatch%20Mar13.pdf)
The finding coincided with the appearance of multiple migrating individuals in the area, including one on the same property as the one above was found, on the same date (first record of a live bird there): https://knnvzwolle.waarneming.nl/soort/view/226?from=2016-04-21&to=2017-04-21&show_zero=0&species=soort+226&prov=0&maand=0&os=0&prov_wg=0&rows=20&references=0&waardplant=0&poly=1&hide_hidden=1&global_tag=0&page=1
