Trail Camera for Wildlife Living in a Tree Hollow ② (Japanese Dwarf Flying Squirrel and Dormouse)

This trail camera has been set in the beach forest on the Masuzawa Trail of Mt. Funagata in Miyagi Prefecture.
It is aimed for tree hollow on “NEZUKO” (Thuja standishii).
The tree hollow is about 2m above the ground and distance between the trail camera and the tree hollow is 1.8m.

This article is written for people who are interested in Japanese wildlife, nature and trail camera.
You will see a part of life of Japanese Dwarf Flying Squirrel and Dormouse.

Good afternoon, I’m Kon.

I have set the trail camera from May 2 to May 29, 2020.

You can see the previous article from the link below.
Trail Camera for Wildlife Living in a Tree Hollow ① (Japanese Marten)

Primitive beach forest at Masuzawa Trail.

Japanese Marten with winter fur used this tree hollow last time.
I found it leave its roost 15-20 minutes after sun set and back before around one hour varies from day to day.

I expected I could see the Japanese Marten with summer fur or something related to breeding this time, however my expectation was beautifully betrayed.

Animals who visit tree

Distance between trail camera and tree hollow is 1.8m.

Japanese Marten visited this tree hollow many times before, but didn’t visit this time.
Instead of it, Japanese Dwarf Flying Squirrel and Dormouse visited sometimes.

Date of visit of animals
May 10, Japanese Dwarf Flying Squirrel and Greater Spotted Woodpecker
May 23, Japanese Dwarf Flying Squirrel and Dormouse
May 24, Dormouse
May 25, Japanese Dwarf Flying Squirrel
Japanese Green Woodpecker visited frequently.

Visiting time of both mammals are very short and they left the tree hollow shortly after taking a grance into it.
Japanese Dwarf Flying Squirrel visited three times so I guess it visit here regularly.
I can imagine two fact below because Japanese Marten who are their natural enemy used this tree hollow previous time and now these two mammals visit.

Japanese Marten keeps away from this tree.
This tree hollow is attractive for Japanese Dwarf Flying Squirrel and Dormouse.

About Japanese Dwarf Flying Squirrel

Japanese Dwarf Flying Squirrel is MOMONGA in Japanese.
There are two kinds of flying squirrel in Japan.
This is the Smaller one.
When it glides, the size is about handkerchief.
Flying squirrel usually eats leaves, tree buds and bark.
It tends to live in the deep forest.
Breeding period is from May to July
Pregnancy period is 30days and usually give birth to 2-3 babies.
Babies are weaned at 1.5 months.
Life span is 4-5 years.

About Dormouse

Dormouse is YAMANE in Japanese.
There is only one species in Dormouse(Gliridae) family in Japan.
It’s head and body length is 6.8-8.4cm and tail length is 4.4-5.5cm.
It is nocturnal and arboreal and lives in matured forest.
It looks mice, but has hairy tail and one distinctive broad line in its back.
Its breeding period starts 1-2 weeks after coming out of hibernation.
It gives birth to 3-4 babies and life span is about 5 years.
It is National Monument in Japan.

What I found this time

Until this time, I thought animals always choose the right size tree hollow for their body size and ignore the place too big for them.
Because big tree hollow is used by big animals and it is dangerous.
But in fact, Japanese Marten use it as his roost and apparently small Japanese Dwarf Flying Squirrel and Dormouse visit it.
If Dwarf Flying Squirrel and Dormouse meet Japanese Marten by chance, they are attacked of course.

What animals are expected next time

Black big ants are living in the hollow.

In addition to the animals until this time, I expect Oriental Scops Owl, Collared Scops Owl and Brown Hawk Owl to visit here.
Masked Palm Civet and Small Japanese Field Mouse are also good at climbing trees.
I think Masked Palm Civet is too big to enter this tree hollow.

Now big black ants are living in the tree hollow.
If other animals want to use it, I want to know how other animals will make it usable.

I just changed batteries of trail camara.
I will check it in one or two month.
