There was a big fight this afternoon in the Nijmegen nestbox.
Ar 17:21 an intruder landed on the ledge and did not go away. Even came into the nestbox. There was a fight, with a lot of hostility.
It lasted for over 1,5 hours. A real territorial dispute.
Now everything seems to have calmed down and the eggs are save.

E' stata una feroce battaglia territoriale svoltasi all'interno del nido. Ora il maschio è sulle uova, ma la femmina, che naturalmente ha seguito l'intrusa, deve ancora fare ritorno...

Jan van Dijk searched the archived images and reported on the Dutch forum (I translated the message for you):
April 6
Till 17:20 all is well; Mariken incubates.
At 17:24 a young female appears on the ledge (she has been seen before in the last couple of weeks). She almost comes in the box, but Mariken keeps on incubating. (Mariken only puts up her feathers)
At 17:34 an unknown adult female comes straight in the box and fights with Mariken. This battle continues for about 8 minutes, and both females step out on the ledge now and again.
From 17:42 till 18:38 the intruding female (leg bands from Germany?) checks the box and shuffles the eggs.
At 18:49 Mariken returns. She rolls the eggs back into the nest cup and incubates till 19:41.
At 19:41 Peter takes over egg-duty and incubates till the next morning April 7, 10:15!!!
On April 7, at 10:15 Mariken takes over incubating and all seems quiet and well.
The question is, did Mariken (and maybe together with Peter) chase off the intruding adult female between 18:38 and 19:41? Anyway, Mariken must have been pretty upset, not returning to the box for the night.
Peter did extraordinary well last night: it was freezing and that stunning male incubated 14 hours on end without changing position!
Let's hope all eggs are intact and that intruding female won't return.
