We have 4 tawny eggs and otters visiting almost every night!

It has been an exciting week! I have regularly been logging remotely onto the tawny box at Yew View and was delighted to see that our female had laid another egg, taking us up to four, for the first time! Tawnies usually lay 2-3 eggs and I feel that this 4th egg is an indication of both her health and the health of the local environment. The eggs were laid over a week:

  • Egg 1- 23rd Feb
  • Egg 2- 25th feb
  • Egg 3 – 28th Feb
  • Egg 4 – 3rd March

She did not start incubating in earnest until just before the 3rd egg was laid, which means about a 4 day difference hatch times. This will impact massively on the final owlet to hatch, as it will be much smaller than its siblings, making survival difficult. It will be totally incredible if this pair manage to raise 4 owlets and it is certainly possible, but unlikely, I fear. Only time will tell!

The eggs will be due to hatch somewhere around April 26th.

I had SO much lovely footage this week, it was hard to decide what to save. I have chosen some highlights. The male has brought back in a few ice this week, along with other prey items to feed the female whilst she incubates…

Our first view of three eggs…..

… more supper!

This mouse came in not long after the last one. Tawnies will stash food in the box if they are not hungry. This footage is from two different angles….

The female is sitting very tight on the eggs, keeping them warm via a brood patch. This is where she has removed the feathers underneath so there is skin contact with the eggs, to keep them warm. You can see her stretch up to expose this area, and then shuffle down to ensure there is maximum warm contact…..

We catch our first view of the fourth egg!

The male did not appear with food for a while, so the female left briefly. She came back with a bird. She may have caught this herself or the male may have done a food pass to her outside the box. I am unsure as to the species of this bird…

It is just wonderful to watch this tawny on her eggs… she is so careful as she gently moves them underneath her….

The male has been day roosting in one of the two other owl boxes we have on site. Here he is in our eco-box.

As if all the excitement in the tawny box wasn’t enough this week, we have had almost daily visits by the otters! The camera platform had moved slightly, meaning that when he ran over it, it tilted. This gave for some interesting footage this week!

Plans are firmly underway for our Yew View otter holt….. with cameras of course…. watch this space!

A Butterfly day

Image
Another sunny day, 24°, light E. A walk alongside the Bunk line from Church road to the bypass. Butterflies were the order of the day with literally hundreds of Meadow Brown on the wing today. They were everywhere. Another 8 Painted Lady seen with some looking very tatty after a presumably long flight and ageing. Best one of the day was a single Silver-washed Fritillary seen flying around a large garden before disappearing from view. Good numbers of Marbled White all along the route. Other species noted were: Small Skipper , Large Skipper , Large White , Small White , Green-veined White , Brimstone (1), Brown Argus (3), Common Blue (8), Red Admiral (6), Small Tortoiseshell (c20), Comma (3), Speckled Wood (2), Ringlet (12) and Small Heath (2). Some thistles were in flower on the edge of a bean field and these held the majority of Painted Lady , Small Tort and Marbled White . Dragonflies: Banded Demoiselle (M&F), Large Red Damselfly and Southern Hawke...

Dormice and Hibernation

Image
A few weeks ago we had our quick dormice pre-hibernation checks to make sure they were all OK for the winter, and confirm how many kits we have bred over the summer. Good news!.. Both our pairs have had large litters of dormice, and so we have many babies to prepare for release next year. As part of the Common Dormouse Captive Breeders Groups (CDCBG) we, along with many other holders across the south, breed dormice as part of the studbook for release out in to the wild. Once out of hibernation next Spring they will all be collected up and released back in to the wild in collaboration with the Peoples Trust for Endangered Species (PTES). We do have two species of dormice in the UK. The native, calm, small and adorable hazel dormouse above. Below is the larger, bitey and much more erratic edible dormouse that was introduced to the UK. You can really see the size difference with both in the hand like this. Both species of dormice are entering, or have already started, to h...
