And finally... Coypu19, on the left earlier seen in the year still in velvet was in the study area during the rut. His father is Longbeys is on the right. Their antlers are very similar in shape.

2 of 2. Eddy 16 and Lalo are evenly matched and after two minutes agree to disagree, moving cautiously away from one another.

1 of 2. Eddy16, left and Lalo right (in both pictures) fight. Eddy16 seems to have the upper hand as he pushes Lalo back, one tip of an antler tine so very close to Lalo's eye.

This is a young incoming stag that we have not seen before, so he has been named Herbert and we estimate him to be about 5 years old. He has been very enthusiastic around the hinds.

Hodges, another incoming rutter, did very well early on in the rut. The nicks in his ears show where he has been injured in previous battles, and are also great for identification.

Here is another set of brothers, Gorgonzola19, left and Gorgonzola20. These boys, along with their brother from 2022, are all that remain of our once illustrious Cheese family.

Scottie has been coming back to the study area to rut for 5 years now. As an incoming rutter, we don't know where he lives for the rest of the year. He is very distinctive with his wide antlers and pale eyes. Saba is ruminating behind him.

It can get confusing when brothers are both rutting, but at least Eddy15, left, and Eddy16 were in different parts of the study area!

We were amazed when 15 year old Sitar10 returned. He was blinded in his right eye a good few years ago in a fight. After this was taken, he must have fought as part of his broken right antler was found!

Sepal09 on the left, our favourite hummel, unfortunately didn't return this rut, so must have died last winter. His son Reggae19 has been in with a group of hinds just recently. We hope he will do well in coming years.

For a number of reasons we have not been posting this rut, but now we're back.
Here is Tokay13 looking like he means business. He was in the Glen early on in the season.

Peridot19 is also back. His father is Wisdom11 (now dead), the stag with the most offspring by far in our group of study animals.

Coypu19, left and his father Longbeys in 2018, the year he was conceived.

Coypu19 is back in the study area for the rut and he is looking very impressive for a 6 year old.

At this time of year, it is very difficult to spot deer. How many can you make out in this picture?

A beautiful, but chilly morning here in the study area, although Askival just has to create a cloud all of it's own.

After 48hrs of wet and stormy weather, we have ventured out in a mere gale to find the Glen flooded.
