The last clutch was on 21 of May, they found a chick of 8-9 days old. The earliest resulted in one chick who was lively and trying to fly, over 30 days of age. They found one empty nest, the chick from which must have been 18 days old, but they didn't find him there; they didn't know the reason. The very first clutch (don't know which exactly) they've never found. The nesting season is over.
The blog is maintained by bird-ringers who also write the logbook posts at the BdL Little Owl forum. In the blog, they report their ringing and nestcheck activities of their research area.
The part of the 2nd text:
translates into:Veel 30+ jongen en ook al veel uitgevlogen. (...)
Op de valreep helaas ook nog een mislukt nest. Eigenlijk hadden er jongen in moeten zitten van een dag of 18, maar de kast was geheel leeg. Altijd weer lastig vast te stellen wat daar gebeurd is.
Op een andere plek nog een jong van 8-9 dagen oud. Teruggerekend is hier het eerste ei pas op 21 mei gelegd. Daarmee is het de laatste van dit seizoen. Helemaal uitsluiten dat het een vervolglegsel is kunnen we niet. Het eerste legsel hebben we echter nooit gevonden.
We found many chicks over over 30 days old, many already fledged. (...)
Unfortunately, at closing time we also found a failed nest. Actually there should have been chicks from about 18 days old, but the nest box was totally empty. Hard to guess what happened.
At another place (nestsite) we found a chick of 8-9 days old, the egg must then have been laid on May 21. That's the latest (date of egg laying) of this season (in the research area of the ringers). We cannot know 100% sure that it is a 2nd clutch - we never found a first clutch.
