wiki (https://en.wikipedia.org/wiki/Dietary_b ... brown_bear):
Despite their reputation, most brown bears are not highly carnivorous, as they derive up to 90% of their dietary food energy from vegetable matter.
They will also commonly consume animal matter, which in summer and autumn may regularly be in the form of insects, larvae and grubs, including beehives.
The diet may be supplemented by rodents or similar smallish mammals, including marmots, ground squirrels, mice, rats, lemmings and voles.In the Kamchatka peninsula and several parts of coastal Alaska, brown bears feed mostly on spawning salmon, whose nutrition and abundance explain the enormous size of the bears in these areas.

thank you! I was away .. a meeting. Video soon
hmmm very small bear? maybe a puppy from that year
part of the head.. it is better to look the video than pictures. I made it brighter and zoomed in a little more. But at no point in time are there any good pictures. But you can assume it's a bear. The noises also suggest it.

When I watched Pikne´s life in Karula's nest, I saw that s/he left the nest infrequently and for a short time. As we know, s/he did not go fishing with Karl II. Pikne was in the nest until the last minute and headed straight south. Consequently, s/he must learn to fish only on his journey south...
most of animal behaviour is innate behaviour or at least have an innate component (the learned behaviour is very intensively researched by ethology, but it is very challenging)

Here is a link about estonian brown bears diet.Solo wrote: ↑August 30th, 2021, 9:56 am wiki (https://en.wikipedia.org/wiki/Dietary_b ... brown_bear):

" Species composition, volume percentage and energy value of bear food. From the collected faeces and gastric contents, we identified a total of 107 taxa: 72 plant and 34 animal taxa (mostly at the species level) and one fungal species (see additional text). Plant residues were found in almost all samples (97%), and their volume fraction was also high (83%). However, calculations showed that plants provided less than half (44%) of the energy value of bear food. However, animal residues were found in only 59% of the samples and were almost five times smaller in volume than plants (17%), but they provided more than half (54%) of the energy value of food (see # 2 for details).
Of the plants, bears had mostly eaten stems or leaves, and in a quarter of cases also fruits (eg berries). Among the herbaceous plants, the most common were expected to be lush and succulent plants: various reeds (eg Norway lobster, wild magpie, common grasshopper, Siberian bearberry) and basket-grassed (eg burdock, porcupine, dandelion). Of the berries, bears had eaten common species such as blueberries, lingonberries, cranberries and raspberries.
We also found one species of mushroom - yellow root nut, of which one bee had eaten the stomach. The majority of invertebrates were ants, of which a total of 21 species were found. In addition, another double-winged larva, a butterfly caterpillar, some bees and a snail were identified from the bear's diet.
The majority of the vertebrate animals identified in the diet are mammals, which were identified in six species: wild boar, raccoon dog, moose, wild goat, cattle and domestic pigs (the latter two are from carcasses taken to foraging areas). In addition to mammals, fish, lizard and bird remains were found."

question: "Bears don't attack storks?"
answer (URMAS):
Why not, if possibility appears! Food is food...
Last year if first time checked that nest (after several years), bear had tried to climb on previous artificial nest probably year or two before. Maybe even broke a part of it, holding nest from down up. Therefore it was necessary to build new construction.
Claws marks on tree were last year well visible. Did not notice these this season, anymore .

Yesterday, Jule embarked on a north-east or crosswind migration across Sõrve Island towards Gotland. On the high seas, the wind became more gusty and the juvenile decided to land on a cargo ship, which did not coincide with its migration direction.
It is not uncommon for birds to use ships carrying large containers during migration, including black storks. The ship's crew may not even notice or pay attention to the "stowaway". It is important that juvenile birds are not frightened on the high seas.
After entering the location on the map in the morning, Urmas Sellis contacted the Estonian Border Guard.
The ship should be "Delta Sailor" and the destination should be near Primorsk Vyborg.
When we receive the evening news we will let you know.
