The Belogradchik Rocks are a group of strange shaped sandstone and conglomerate rock formations located in the western part of the Balkan Mountains in Bulgaria.
The Northern Fulmar (Fulmarus glacialis) is an interesting Arctic bird, which superficially resemble seagull, but is in fact related to the Petrels. Unlike the Seagulls, the Fulmars have stiff wing action when they fly.
On the Shetland Islands I found them to be abundant, mostly around places with safe from cats and rats cliffs and rocks. The subspecies I filmed is Fulmarus glacialis auduboni (the one living closer to the North Pole is F. g. glacialis) and the morph is the light one, which is typical for this subspecies.
It is only few seconds long video, but that was all I managed to snatch of the Shetland Wren after chasing them for 3 months. Its not that they are particularly uncommon, but they move a lot and normally while I'm getting my camera out they are gone and I feel really unlucky with them.
So the Shetland Wren (Troglodytes troglodytes zetlandicus) is not a separated species of wren, but rather endemite subspecies living on the Shetland Islands. There is also another subspecies living on the Fair Isle, but I didn't had to go there and missed the opportunity to see it. And as the Wikipedia says the differences from the more common T. t. troglodytes are its darker and more rufous-brown colouring, with a heavily barred underside, the barring extending from belly to breast and the bill is stouter and longer and it has stronger legs. An estimate of the population, from the start of the 21st century, was of 1500–3000 breeding pairs.
Some video clips from the Magura Cave. Its pretty big one with 2.5km (1.6 mi) total length. It is in the form of a passage and when somebody enters from one end exits through the other. It is interesting because contains human remains from about 40 000 years ago and was home for some of the last Neanderthals. Also it has inside prehistoric wall paintings made of guano and carbon dated from 11 000 to 8 000 years ago. And particularly interesting for me are some of the depictions of Ostrich and Giraffe-like animals made about 11 000 years ago. I made some research and couldn't find anything like that living at the time in the area or even Europe in general. Strangely enough this issue was not researched and very few people even paid attention. I guess these that know that giant birds haven't lived among the early Europeans are different people from these that analyse ancient paintings or with other words Palaeontologists don't mix with Archaeologists. Also there are depictions of mushrooms, so the use of the magic ones is not out of question. The Sun-like paintings have corresponding number of rays and lines and suggest early attempts for creating calendars.
All that was amazing, but there were a vandalised paintings and rocks from the time when the cave was freely open for anybody. Nowadays one can enter alone after paying small fee, but generally the halls with the paintings are visited with guides.
TLDR Big cave with prehistoric wall paintings. If you visit Bulgaria one of the top 10 things to see.

Stairs in the Magura cave
First hall in the Magura cave. Tribe of 300 prehistoric people lived here. Remains of Cave Bear, Cave Hyena aand other prehistoric animals were found. Scientist say that Neanderthals lived in the cave, too.
Stalagmites in the Magura cave

The walks are well lit and marked in the Magura cave

Nearly vertical drop in the middle of the cave after the paintings hall section
Entrance of the "Art Gallery" in the Magura cave
One of the most interesting prehistoric paintings in the Magura cave. Dated 10-11 000 years old, depicts hunting scene and Ostrich- or "big bird"- like animal, which shouldn't have existed at that time and place.
The animal depicted in this prehistoric scene even without the "bird" are interesting and strange enough
