Kovat ajat tulossa Jonolle

Hi everyone there is clear evidence that the aggression has started as it was captured yesterday 1 Nov 2014 by other photographers. Bo is concerned that the adults will chase Jono out of his natal home range before he is ready. I have calculated that the aggression has started 9 days earlier that last year with Nessi. the (Ernest Porter)
This early aggression aimed at their offspring is yet too early as he has only been 7 weeks off the nest. Usually, such behaviour is only evident in the region of 10-11 weeks and there is no precise reasoning as to why the juvenile is being harassed this early as there is ample prey and the adults have provided adequately.
This process cannot be reversed in any way because as soon as the onslaught commences, Jono will have to learn to defend himself from Thulane and ultimately Emonyeni. The flight path ahead for Jono will be an uncertain journey and no matter how much resistance he will present now, the more intense will the onslaughts become. A gradual process that can last 3-4 weeks, the following weeks are going to be extremely difficult for Jono as he understands little of the adults’ behaviour towards him and why the incessant harassment. This lesson however, will be of great value to Jono later in his life when he has a mate and offspring of their own and only then will he come to understand what is happening to him now will have a repetitive bearing later in their lives.
Not easy at all as in his first year away from his natal home range, he only has a survival chance of a lowly 20-30%, which is rather poor for such a large species. Starvation is by far the biggest obstacle that he has to overcome…taking into consideration that he has never hunted for himself…the adults also don’t teach him how to hunt, it is pure instinct that triggers his brain that he must eat in order to survive…

Voi, voi! Kovaa on Jonon elämä ja sitä saa ihmetellä, miten mustakotkia enää on olemassa, jos ensimmäisen vuoden selviämisprosentti on vain 20-30%! Toivottavasti Jonon vaisto ohjaa siitä selviämään ja metsästämään! Kuuma kesä on vastassa. Kuinka uhanalainen tämä laji oikein on?

Jono lensi aamuvarhaisella pesälle Em (?) mamman kanssa.
Emo lensi pois ja Jono asettui pesälle auringon lämpöön

Jono on tullut taas kotiin nukkumaan

Tänää aamulla mustakotkien naapuri muuttohaukka oli pesällä istuskelemassa
Pesän oma väki ei ollut kotosalla

Ou, miten hieno havainto. Olin juuri Ausseissa kookaburran pesällä, jossa joku kirjoitti, että joutuu olemaan siellä, kun ei näe enää Jonoa. Saakohan googlettamalla selvitettyä pesän ja puiston etäisyyttä?

Teppanalle iso kiitos tuosta Jono-videosta!Mukava nähdä että kaikki on hyvin.Siipikään ei näy roikkuvan enää

Tänään ei ollut Jonolla hyvä päivä,emot häätivät pois pesältä ja lähtivät vielä taka-ajoon.Luultavasti taistelu jatkui vielä pesän ulkopuolellakin.Jono näytti alakuloiselta, olisi niin halunnut kuulua perheeseen, voi Jono raukkaa...

Jonolla on kovat ajat edessä. Onnea matkaan mustakotka nuorukainen
Mustakotkilla se vaan menee näin, jonakin päivänä Jono ajaa oman poikasensa reviililtään

Black Eagle Project Roodekrans

Black Eagle Project Roodekrans Verreaux’s Eagle aggression towards their offspring
The aggression of verreaux’s eagles towards their offspring exists because verreaux's eagles are extremely aggressive and territorial eagles. It is considered normal behavior for them to chase their offspring out of their territory about 9/10 weeks after the juvenile has fledged from the nest.
The aggression is not swift and continues for 3-4 weeks before the juvenile is actually chased out of the natal home range. The adults don’t harm their offspring in these aggressive attacks, but they certainly give them a good scare, especially in the beginning of the aggression. Later on the juveniles participate and even return the aggression towards the parents.
Interestingly the adults still bring prey for their offspring while the aggression period is in motion. You can imagine the confusion a juvenile must experience when being chased and attacked in the morning and then later seeing his parent bring a nice, juicy snack for him to feast on.
In my opinion it is life lessons for juvenile verreaux’s eagles, which they will need in order to survive as they live lives filled with aggression. One day these juveniles will have to be able to defend their own territories and be aggressive hunters in order to survive, they also have to be aggressive towards their offspring.
The juveniles only start hunting for themselves after the parents chased them out of the natal home range.
Jono will probably be chased off by approximately mid-December according to normal aggression behavior. But we are dealing with wild eagles which have a mind of their own.
