July Squares: (Eurasian) Blue Tits.

A contribution to Becky’s July Squares: Blue photo challenge.

Having posted a grumpy Great Blue Heron as part of the challenge it didn’t occur to me how many birds there are with blue in their common English names until writing this post. Expect to see a few more bird species before the end of the month.

Feeding Recently Hatched Young.

One from the archives taken in Cheshire in the late 1980s.

Having documented the complete nesting cycle of a pair of Eurasian Blue Tits in 1987 I went on to photograph other species in different nestboxes over the next couple of years.

Here an adult Great Tit (Parus major) is about to feed some recently hatched young with a small yellow green caterpillar. While it looks as if the bird is looking at the camera it was just the timing of the shot. It was dark inside the nestbox, I was releasing the shutter a second or two after hearing an adult land at the entrance hole.

The new Weekly Prompt Photo Challenge is Old and New.

I had a few ideas for the challenge before thinking of some of my nestbox shots of adults feeding young.

This shot is quite a rare event with two adults in the nestbox together, normally there’s only a single adult in the nestbox once they’re feeding young. Taken using a specially constructed nestbox in Cheshire, England.

Eurasian Blue Tit nesting story

The last nestbox photo.

After the last young Eurasian Blue Tit left the nest I started checking the nestbox in the early morning and late evening. I was checking to see if any of the birds returned to use the nestbox as an overnight roost site.

This is what I saw 48 hours after the last youngster left. Those are Bird Fleas on the sides of the nestbox. I spent the rest of the day itchy, psychological as I never found a Flea or bite on me.

The eleventh young Eurasian Blue Tit.

The eleventh youngster in the nestbox wasn’t ready to leave. All its siblings have left and are being fed and taught to survive by the adults. At times I could hear one of the adults calling to encourage the youngster out of the nestbox but it wasn’t leaving. Despite having ten young to look after the adults would still bring in a caterpillar occasionally for the one left behind.

I checked that the youngster was still in the nestbox several times during the day and it was still there that night. I got up the following morning and the nestbox was empty. The bird must have left the nestbox as soon as there was some light in the sky.

Left alone.

It would occasionally get up at the entrance hole but wouldn’t leave the nestbox.
