Trying again

After visiting the nest site each morning and evening to check the mink trap this week, I was becoming increasingly concerned at the lack of any sign of the kingfishers, so on Saturday I decided to set up my hide and do a long stint at the nest site, to see if there was any sign of the kingfishers returning.

After half an hour the male Kingfisher turned up (he seems to have lost the tip of his upper beak during the week), and then after he’d been sitting opposite the nest for about 10 minutes, I was amazed to see two more kingfishers arrive. The male immediately flew across to them and a few seconds of aerial chasing ensued, until eventually all three birds settled in adjacent trees. I was able to observe the new arrivals with my binoculars and it became clear immediately that these were juveniles, presumably from the first brood that fledged 6 weeks ago.

The juveniles flew backwards and forwards across the river for the following hour, hovering near the burrows and repeatedly entering all of them. The adult male seemed to be content to observe and didn’t appear to display any aggression towards them. Just as I was getting my head round this development, a fourth kingfisher arrived and I was greatly relieved to recognise the adult female, who had been incubating when the mink raided the nest.

Half an hour later the juveniles had left, and the adults started to pay more and more attention to the burrow where the first brood had been raised. It soon became clear that they were concentrating their efforts on this burrow, taking it in turns to enter for several minutes at a time, while their partner watched on from the branch opposite.

I returned on Sunday and the adult pair were still present, continuing to work on the burrow, with signs of renewed mating behaviour taking place. I observed a couple of fish passes by the male and a couple of tentative attempts to mate. I think that once the female is happy that the burrow is ready she will allow the male to mate and egg laying will then start again and continue for the next week or two.

I’ve seen no sign of the mink since the second day I had the trap out, when I caught a second juvenile. I assume the adult female has moved the remaining kits to another location, but this area of bank is still part of her territory and I’m concerned that the new kingfisher nest is not going to be safe from her as things stand.
