Kendi izaugusi un pamazām vecāki sāk izrādīt, ka viņai jādodas plašajā pasaulē un jāuzsāk dzīvot patstāvīgu dzīvi, medīt...
Tas notiek tāpēc, ka Verro ērgļi ir ļoti teritoriāli. Agresija pret jauno ērgli sākas 9-10 nedēļas pēc tam, kad tas izlidojis no ligzdas, un ilgst 3-4 nedēļas. Agresijas rezultātā mazulis netiek savainots, bet tiek iebiedēts. Šajā laikā vecāki joprojām turpina mazulim piegādāt barību. Tas viss droši vien jauno ērgli patiesi samulsina. Tomēr liekas, ka tās ir arī ērgļu dzīves skolas mācībstundas...

Black Eagle Project Roodekrans 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 a big part of this is life lessons or training 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.
