Wildlife Wednesday: The song thrush’s nest

A few weeks ago I posted about the abundance of bird nests in the wood and some were in awkward, inconvenient places.

A song thrush had nested under the bonnet of the dumper truck meaning it couldn’t be used for several weeks while mother and father thrush hatched out their eggs and reared their brood.

The chicks fledged successfully and the nest could then be removed. Leaving the nest could be a potential fire hazard as it was located right on the mechanics and electrics of the vehicle. The dry twigs could ignite easily but also mice like to make use of old nests and mice do not go well wires! It also may have tempted other birds to nest in there. Elsewhere in the wood a pair of robins have built a nest on top of a used thrush’s nest and it currently has young in it. We didn’t want the same to happen with the thrush nest under in the dumper so it was best to remove it.

Holding a nest allows you to get a really good look at how intricate the design is. The inside is a perfect circle with a domed bottom, evenly formed from a layer of mud. It’s extraordinary how birds are able to create such accurate geometric shapes, and be so artistic, all with their little beaks

For comparison, this is a blackbird nest. It is very similar in size and construction but the main difference isn’t visible here. Blackbirds line their nests with soft dry grass but it will have been worn away by the chicks leaving the mud layer beneath that makes it look similar to the thrush’s nest.

Here are the two nests side by side. They are very similar, probably because both the song thrush and blackbird are members of the same family, Turdidae, so have similar behaviour traits.

Aren’t nests just amazing?

PS. Have you had any nest in your garden this year?
