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.

Last to leave

The first brood of kingfishers has fledged and less than a day later only one fledgling remains near the nest site. I saw 3 youngsters Thursday evening, but by the following morning there was just one left at the nest site. I’ve spent most of Saturday and Sunday walking the river, but I’ve only spotted the adult birds, so I’ve no idea where the youngsters have gone or how they’re faring now they’re out of the nest burrow. On a positive note, from the little I saw of them, they seemed full of life and quite capable of flying up and down the river at pretty much the same pace as the adults. I’d love to know how they get on, but I suspect I’m going to be disappointed, though I’ll continue to watch the river in the hope that I might stumble upon them over the next few weeks.

Back at the nest site, the female is spending a lot of time in the new burrow. When she’s not in the burrow she seems to be staying close to the nest, sitting in the tree opposite the nest preening or flying 20-30 yards upstream to another perch she seems to have taken to. The male returns every hour or so and regularly passes fish to her and attempts to mate. After the regular feeding of the young that’s been going on for the last few weeks the nest site suddenly feels very quiet. I’m actually a bit taken a back by the speed with which the youngsters have left the area. I’d kind of hoped they’d stick around for a few days before the adults booted them out of the territory, but as things stand it appears that they’ve left!

Fish pass & feed

Although the chicks are still a week or so from fledging, the adults behaviour seems to be shifting back towards mating. I’ve seen several fish passes, where the male brings a fish and presents it to the female, a behaviour which is a typical pre-cursor to mating. When this was happening before the first brood, the female would immediately eat the fish and hang around waiting for the male to bring her another, whereas now, with hungry mouths still to feed, the fish is taken straight over to the nest burrow.

I know that once the young emerge they will only be tolerated for a few days before being driven out of the parents territory. The fact that breeding behaviour is already underway suggests that this pair are not going to waste any time getting a second brood underway.

If you’re curious about what happened after the fish passing, keep checking the blog, as I have a rather special film clip coming soon.
