Did you know that there are six million breeding pairs of blackbirds in the UK, each pair capable of producing up to four broods each year? No, neither did we.

Blue tit nest part 3

In the header photograph, the blue tit’s eggs are lying in a cup shaped nest lined with soft feathers that are obviously intended to keep the eggs warm. But around the edge of the cup there are larger feathers; their purpose is not so clear.

Blue tit nest part 2

After yesterday’s video post, a reader asked what triggered the blue tit female (it is always the female blue tit that builds the nest) to stop collecting moss and to begin collecting what he called fluffy stuff. While failing entirely to find an answer to his question, I found a treasure trove of research into blue tit nests and the materials they use to build them.

Blue tit nest

Anybody want to guess how many blue tits are building nests in the reserve today? Here’s how it’s done.

Blue tit colours

The blue tit (Parus caeruleus) has been classified as sexually monochromatic, which means that male and female are the same colour. This classification is based, though, on human colour perception, not on blue tit colour perception.

Muntjac

A message from an early-bird dog walker:

I spotted a Muntjac deer this morning, about 5 o’clock whilst walking my dog, who luckily is always kept on his lead. It was In the hedgerow that runs along the path from the carpark towards Studley, just one by itself only. Is this a species you are aware of?
I was very surprised to see it so close to a built up area which has quite considerable footfall. But for well over a year I haven’t haven’t seen the larger deer which frequented the park.

Returning chiffchaffs

Has anybody heard our chiffchaffs yet? This is the time of year when they come back from the Mediterranean and Africa to nest in the park and their unmistakeable call is a welcome sign that spring is here, no matter how much it rains. Message or email us if you have heard them .

Barn owls

Most years, in March, the reserve is visited by a pair of barn owls. As barn owls mate for life, this is probably the same pair each year looking for a nest site. They always set up a temporary roost in one of the oak trees in the hedge in the centre of the field between Church Lane and Lambrok Meadow and hunt across our fields in the early dawn.

Have any of you up-with-the-lark early morning dog walkers seen them this year? Please let us know if you have.

Great tits can be very loud at this time of year as they search for territory and a mate. They sit high in the trees and shout. It is a distinctive repetitive call like a creaky gate. Listen out for it.

This great tit is in the willows by the decorated bridge, sitting up up among the branches and making a lot of noise
