she is preening him


6:17 she is stretching out wing and leg


6:27 Mating (3)

[Liz01]

6:39 she jumps on the left branch & back into the nest

6:45 her plumage /I took these pictures when I read that she might be too young. I never understood how you could tell from the feathers. She looks totally grown up.

Birds do not live with the same feathers all their lives. They grow, wear out, fall out and grow new ones instead of the old ones. After obtaining the costume of an adult bird, which takes place at the age of 2-3 years (even this is not yet known exactly!), The black stork changes its feathers continuously throughout its life. Storks cannot afford to lose airworthiness by replacing "all feathers at once" (as is the case with some waterfowl species), so the feathers that are important for flying - feathers (large feathers) and angles (tail feathers) are gradually changing. Feather changing is an energetically very expensive process, as are laying eggs (for mom) and feeding babies (for both sexes). Probably, therefore, during the seasons when birds raise their young, there is no intensive change of feathers in nesting places. Rarely does a worn airplane or cornice fall out (and begin to grow back). In the off-nesting seasons, the feather change appears to be more intense in the nesting areas, but the main feather change apparently takes place in wintering areas where there is no other energy stress. One feather appears to have served the bird for at least two, possibly three years.

Feather that is older is less rigid and its ends become finned (because of worn hooks that hold the feather rays together). New feathers have smooth, flat ends. In the years when the birds are under a heavy load (a lot of children and probably not enough food for themselves), the feathers wear out much more and therefore at the end of the season the bird no longer "looks after itself", even compared to the situation just a few months ago. Between seasons ("this year" compared to "last year" or earlier), part of the feathers have been changed for each adult bird, even if it is the same bird. Therefore, using the visual condition of the feathers (finned ends or not, broken grooves, etc.) as a criterion for identifying a bird is as productive as judging whether a famous singer is still the same person, based on the cut and / or outfit of her costume. colors every time you perform ... So far, there is only one surefire way to determine a bird 's identity - a ring on a leg, whether someone likes it or not.

Pēc Māra Strazda lūguma, šeit ir viņa atsūtītā ziņu tiešraides skatītājiem:

"1. Pēc apspalvojuma, t.sk. galvas krāsas, knābja un kāju sarkanuma melno stārķu vecumu noteikt NEVAR. Tas ir tikpat gudri, kā spriest, ka, teiksim, cilvēks ar līku degunu ir vecāks par cilvēku ar īsu un spicu degunu. Pēc izskata ir atšķirami putni līdz 2 gadu vecumam, bet tad vēl viņi neligzdo.

2. Tehniski ligzdošanas vecumu sasniedzis putns (kādi ir visi kamerās redzamie) VAR ligzdot. Mazākais vecums, kādā ir zināms, ka jauna M ir izdējusi olu, ir pilni 2 gadi (trešais kalendārais gads). Neviena ligzdā esoša M, kas ir pieaugušā putna tērpā, nav par jaunu, lai izdētu olu.

3. Lai izdētu olu, M nepietiek ar apaugļotu olšūnu. No olas svara un tilpuma lielāko daļu veido barības vielas, kas M ir „jāsagādā” ļoti īsā laikā. Ola veidojas 48 stundu laikā. Ja šajā laikā nav pieejams pietiekams daudzums augstvērtīgas barības, iespējams, ka olas neveidojas tikai tāpēc – jo nav no kā to izveidot (bet ir zināms, ka putni var neligzdot, tāpēc, ka „negrib”, tāpat kā cilvēki, kam ne visiem ir bērni). Laba liecība tam, cik labā kondīcijā M ir, ir viņas mēslu strūklas garums (un nokārtošanās biežums) – labi paēdušam putnam strūkla ir krietni garāka par 1m (vērtējums aptuvens, pēc fotoslazdu un webkameras bildēm), t.i. garāka par paša augumu. Ja ar to viss šķiet kārtībā, tad neligzdošanai visdrīzāk ir citi iemesli, kurus kamerās redzēt nevar."

M means Matite = Female

GT :
At the request of Māris Strazds, here is the message he sent to the live viewers:

"1. You CANNOT determine the age of black storks by plumage, including the color of the head, beak and red legs. It is as wise as judging that, say, a person with a crooked nose is older than a person with a short and pointed nose. birds are distinguishable in appearance up to 2 years of age, but then they do not nest.

2. Technically, a bird that has reached nesting age (what are all the ones seen on the cameras) CAN nest. The youngest age at which a young M is known to have laid an egg is a full 2 years (third calendar year). No nesting M dressed as an adult bird is too young to lay an egg.

3. A fertilized egg is not enough for M to lay an egg. Most of the weight and volume of the egg is made up of nutrients, which M must "provide" in a very short time. The egg is formed within 48 hours. If there is not a sufficient amount of high-quality food available at this time, it is possible that the eggs are not formed simply because there is nothing to create them from (but it is known that birds can not nest because they "don't want to", just like people, not all of them have children ). A good indication of how good M's condition is is the length of her dung stream (and settling frequency) – for a well-fed bird, the stream is much longer than 1m (estimation is approximate, based on photo traps and webcam pictures), i.e. taller than his own height. If everything seems fine with that, then there are probably other reasons for not nesting, which cannot be seen in the cameras."



Ah, I understand, yesterday they blamed Urga because there was no egg yet. They thought she was too young. And I thought it was always the same.
Nothing is as expected and the female is to blame. Then you lose your desire

BTW: I document every PS .Healthy means string is long

already Juli 2021/All of Maris' other facts are also interesting
The first part of the sentence can be considered correct, but the second is complete nonsense. Birds can be safely distinguished at the age of two, when they are characteristically variegated - some feathers as young, some as old, and, to a lesser extent and perhaps not all birds, this appearance is maintained at three years of age. After that, the birds change their feathers continuously, presumably, each of the large feathers changes after 2 (or even 3) years. Worn feathers are dull, the older, the duller, re-grown are shiny with a bronze sheen. Neither in terms of "brightness" nor variegation, as far as adult birds (from 4 years of age) are concerned, their age CANNOT be said. It is safe to tell the age of a bird if it is ringed and the age is known from the ringing data.

and his beloved BS .. battle about a white stork nest


Although the white and black storks are from the same family, it can be figuratively said that they speak different languages and do not understand each other. The result of such communication can be seen in Skrunda. The employees of the Skrunda Culture House were very surprised when they saw the black one in the white stork's nest. The whites have not been at peace with it. Who will really be the master of the nest?


Thanks to a FB Friend for the video Link

EDIT:
Maris S said:

Most likely, he is the only one not only in all of Latvia, but maybe also among the black storks that are alive at the moment. Perhaps that bird has grown up in a white stork's nest and identifies itself with a white stork, but biologically of course it is not. He has innate behavioral frames. Those white storks, whom he would like to cling to and maybe find a partner for himself, do not understand him. What black storks are roosting flight, the white one may perceive it as an attack and does not understand why the "black fool" is flying after him

Is from my FB Messenger..
