Every time we brush the bunnies, we save their fluff, and, at the start of spring, place some of it in an old bird feeder, so the garden birds can use it for their nests.
Last year, we watched several birds gathering the fluff. A pair of blue tits took some of it to the nest box.
Unfortunately, they abandoned the nest before laying any eggs.
This year, however, we've had the pleasure of watching a pair of blue tits successfully raise their family in the box. The blue tits have been regular visitors to our feeders for a long time, and have often appeared on our trail camera.
In the 27 years that we've had a nest box on the tree, it's the first time birds have laid eggs in it – sadly, this is probably a sign of the times, with so many gardens now turned into 'yards', devoid of trees or shrubs, leaving birds very few natural nesting sites.
Nesting started towards the end of March, when we noticed a blue tit spending a lot of time every day pecking at the box – around the entrance, on the bottom, and inside. Nobody knows for certain why they do this – suggestions for this behaviour include: to check the structure; to round any edges and adjust the entrance hole; to remove any splinters; or to mark territory, telling other birds that the nest site is occupied. Whatever the reason, the behaviour continued on and off for a few weeks!
Next came the careful curation of nesting material, starting with vegetation, and some of the bunnies' hay they found in the compost pile, and finishing with beakfuls of fluff from the feeder. Then all went quiet. It was impossible to know whether a blue tit was sitting inside the box, or whether they'd abandoned it.Then, on 8th May, they started going in and out of the nest box again, this time collecting food from our garden and further afield. These trips were infrequent at first, but increased over the next few days, presumably as all the chicks hatched.
We kept our distance, but they seemed to know we were safe and were happy for us to stand a couple of metres away and watch them going in and out of the box. Perhaps they realised we'd keep the magpies away.
When the chicks were just over a week old, we could hear them clearly, even from inside the house! The parents were extremely busy bringing food to the nest, throughout the day. Apparently, each chick can eat one hundred caterpillars per day!
On 25th May, we saw the baby chicks for the first time! They started looking out of the nest box entrance, catching their first glimpse of the world. Below is a compilation of footage of their last day in the nest box.
Aware that they would probably fledge within the next few days, we ensured the garden was as safe as possible. Already we have wobbly clematis trellis along the top of our fences, which we installed to make it difficult for cats and foxes to enter, so we made sure that there were no gaps. We put a willow fence panel in front of the pond, which lies just in front of the nest box tree, and made sure there was nothing in which a new fledgling could become trapped.
The following morning, on 26th May, when the chicks were probably around eighteen days old, they fledged. The little one in the video below must have been last out, and took much longer to fly away. He/she had a lucky escape – first, from a squirrel, who was sniffing around the area, when we looked out early that morning; then from nearly being trodden on, as we went to scare away the squirrel. We'd rushed out, thinking the squirrel could take one of the chicks out of the box; little did we know they'd already left the nest, and the squirrel had been perilously close to the one on the ground.
Following an anxious few minutes when we watched from a distance, hoping the fledgling hadn't been abandoned, we were relieved to see the parents fly back to feed and encourage him/her to fly. They also peeked into the nest box, to check it was empty.
It took about an hour, but finally the last fledgling flew away, and the garden felt oddly quiet.
After 27 years of leaving our bunnies' fluff out for the birds, we have finally seen fledglings which had been born in a nest lined with the soft fur, and even saw one take shelter beneath the bunny bush! Hopefully the chicks will survive, and the parents will come back to the nest box next spring.
Stay safe, little fluffball |
