A new burrow


It’s just over a week since the first brood fledged and the adults are engaged in excavating a new burrow. It’s come as a bit of a surprise to me, as the female seemed to have settled on an existing burrow about 6ft to the right of the one that the first brood were raised in. She’d been spending a lot of time in this burrow, and I’d seen the adults mating again over a week before the first brood fledged (I was beginning to wonder if they were getting a new brood underway before the first one had even fledged). I have no idea why they’ve decided to dig a new burrow after seeming to commit to the old one, but it looks like the new burrow is going to be home to the second brood and I’m waiting now to see when they settle back into the behaviour patterns typical during egg incubation.

While the burrow is under construction, both birds spend the majority of their time at the nest site. The bird that is not digging stands vigil nearby and emits occasional calls which are quite subdued in comparison to their normal call, this presumably lets the bird in the burrow know that they are present and that all is well outside. When the bird in the burrow emerges, the other often flies straight into the burrow, seemingly keen to see what the other has accomplished and do some work themselves.

Another thing I’ve noticed during this phase is that the male seems very keen to pass fish to the female, but for the time being she’s clearly not interested. I assume the fish passing, and any subsequent mating is on hold until she is happy with the new burrow.

During the time I’ve spent observing the digging of the new burrow, I’ve also seen kingfishers flying past the nest site at speed, occasionally prompting a response from the resident adults. I can only assume that this is one or more of the fledglings; I wonder how long their presence in the adults territory will be tolerated.
