After some bussy days and really no time for TN, here I am again :>

The spring is comming very slowly to central Poland, so today a winter picture of a real winter sleepyhead! ;>

This is Myotis daubentonii (Kuhl, 1817) (Vespertilionidae) or Daubenton's bat (in Polish: nocek rudy)

Anyway, according to the title of presentation I think it would be good to write a few words about dormancy in bats and other creatures :>

A dormancy is understood as a state of inactivity and metabolic depression in animals, characterized by slower breathing, and lower metabolic rate. Depending on species, ambient temperature, and time of year it may take several days or weeks.

In general it can be divided into following categories:

Hibernation - a mechanism used by many animals to escape cold weather and food shortage over the winter.

Estivation - similar to hibernation, except it is used in the summer to escape high temperatures.

Diapause - a state of metabolic dormancy that requires specific stimuli to trigger and release, which occurs mainly in insects.

Torpor - regulated hypothermia for less than a day, often used by birds and bats.

According to all this written above we can note that bats "prefer" both hibernation and torpor. Really most of European Chiroptera species do not "sleep" all winter, but they wake up many times during this season. They can not only fly in these days, but - if the weather is good, and temperature not too low - even from cave to cave to change their winter shelters.

Picture was taken in old German railway bunker (IInd World War) localized in the Spala Landscape Park.

As always thank you in advance for your comments and critiques. Please feel free to watch also my earlier bat presentations :>

Hi Radomir

Lovely shot - very good detail and exposure. I have no ides about ID - I will look at your previous postings and get back if I think I know.

My best guess is a Brant's Bat . . . .


Hi friend Radomir,

What a beautiful bat in hibernation and splendid close-up capture indeed. I liked its earlaps:-) Your capture is excelent as usual. TFS.
Have a nice weekend!


Now I understand the English word "torpor" better, Radomir!
So this bat is in a state of torpor.
The fellow has chosen the place for prolonged sleep very wisely, except that you were cleverer and shot him in such a wonderful way without actually disturbing it.
The aminal's posture says it all.
Great image and thanks for sharing it.

All the details of a wooly animal to capture fully as big Radomir. Actually this is one of the best chiropteran close ups i have seen in TN.


BTW, i think it may be Myotis dasycneme due to coloration. Ahmet Karataş (rousettus) is te expert here, maybe he can have the exact guess.

Hi Jaskula
This is a perfect capture of a hibernating bat. Wonderful composition. Thanks for sharing this beauty.


A fine macro-shot of this bat obviously in torpor Radomir, and glad to see you back after a while my friend. The ID on this bat would be easy, but not for me, a proper bat expert (like our friend Ahmet - rousettus) should do it I think. However our hairy friend here looks as if begging for a proper ID, a little patience my friend, till Ahmet returns from the field!

Hello Radomir,

Superb picture of this bat. Good composition. Very good exposure and great sharpness.

Hi Radomir,
This is a fantastic image of the bat in hibernation.
You got really close,and have captured such great detail and colour.
Did you know that the only two native mammals in New Zealand are two very small bats.
All other mammals were introduced in the last 200 years.
You've done a great job of photographing this one.
Well done.

Hi Radomir.
I have read your note with great interest and wanted to know where you have captured this animal. You have given answer. Very nice specimen and as usual for your outstanding reproduction of the scenery and animal. You have reproduced every hair and skin texture brilliantly. Flash work is great too. Bravo. Excellent job.

Ummm Pipstrelle? That's the only one I know :-)
Razor-sharp image anyhow.
Great detail and superb clarity.
Very good composition.
Nice lighting.
Well done Radomir,


Hi Radomir,

ok, ok, lets see... no idea. Myotis brandti? And that would be guessed only from looking at your bat gallery, not from the Mammalian guide. But be it, a very nice shot it is, the animal is actually lying and not hanging while in torpor. The best of all: good to have you back on the air, Radomir!
Best regards

Hello Radomir,
Great shot of a hibernating bat with good sharpness and from a fine POV that should allow a bat expert to give and ID.
As I am no expert I can only guess that as this is very dark it is Myotis mystacinus (or possibly brandti).
It would be interesting to know and thanks for sharing it!
Best wishes, Ivan

Hi Radomir,
Wonderful shot with immaculate sharpness on its fur. Fabulous sleeping posture and you have captured it quite nicely. Though I am not able to identify it and I am scared of bats I still like it shot. Very educative note and very nicely composed. Kudos.

Hi Radomir, unusual view of lovely sleeping creature, wonderful details and excellent sharpness, perfect focus, very well done, ciao Silvio

Hi Radomir,
it's not often the word 'cute' is associated with Bats, but it definutely applies here!
What a lovely shot of this sleeping Bat. Excellent detail and POV, amazing that you can get such a close shot - very impressive, well done!

Hello Radomir,
You do set us some really difficult tasks!! This is a great shot of a bat that is very similar to other bats! :-)) But, it's got a black nose so I wonder if it is a Myotis mystacinus?? Anyway - this is a great shot showing fine details and colours. I'm just a bit puzzled by the curly fur! Please tell us the answer soon!!
TFS and best wishes, Ulla
Sorry, P later

Excelente pose de este curioso animal desconocido para mí en una pose de latencia como tu muy bien has explicado. Realmente instructivas tus notas.

Hi Radek,
Today I knew that bats hibernate. A beautiful capture with excellent sharp details. Thanks a lot for sharing.
