Eher früher. Las gerade von 1-2 Jahren Halbstarkenaufenthalt in Afrika statt 3 Jahren.
Mit 2 Jahren erfolgt bereits die Geschlechtsreife.
Evtl. handelt es sich auch um ein fremdes Jungweibchen auf der erstmaligen Partnersuche (Seeadler sind ja monogam).
Hat die Natur evtl. so eingerichtet: Kommt Frau Özil, muß die Neue (man nennt sie im Forum schon "Oxana", d.h. "die Fremde") weichen, sollte unserer Frau Özil aka Piret was zugestoßen sein, steht die Neue bereit.
Mal was zum Gruseln für die Damenwelt (aus einem jamaikanischen Seeadlerforum - links unten). Voodoo inclused!
The longer the time interval between mates arriving on the breeding site, the more likely it will be that the first arriving mate will attract or be attracted to a new mate. Yes, Ospreys do mate for life as far as we know, but that bond needs to be reinforced each spring by the arrival of the second mate. If too much time elapses, the instinct to wait for their mate wanes, and they will accept another mate since the instinct to breed is far greater – and more important – than the instinct to wait for a mate that may have perished over the winter.
So xyz arrives to find that his mate has a new mate – what happens then?
In most cases, the late returning bird will drive off the new bird as the bond between the old mates will be stronger than the newly formed bond between the old mate and the new mate, especially if the new mate is a young bird. We often see three Ospreys on a nest and conflicts between two of them early in the nesting season. These conflicts are usually short in duration and no one gets hurt in the process. However, once I found an adult Osprey dead in the nest while two adults went about their business of egg laying and rearing young. I do not know if the dead bird was a former mate or an intruder.

Meine Frau heißt übrigens auch Oxana :neutral-face
Kam die auch eines Tages zu dir in die Wohnung?
..wenn man den Faden jetzt weiterspinnt......
Der Vergleich bezog sich mehr auf das akustische Stehvermögen als auf "das Andere) .
Vor 6 min. wilde Begattung!!!

ist es denn überhaupt sicher, dass es madis ist?
Ist natürlich nicht so rosig wenn man bedenkt, dass dort bald mal Nachwuchs aufwachsen soll.
Angriff ist vorbei. Es dürfte sich dabei auch um die "Fremde" Dame handeln, da kein Ring zu sehen ist.
lt. looduskalender - dort wurden vergleichende Bilder von letztem Jahr zu heuer von den Gefiederfärbungen gepostet - soll es zweifelsfrei madis sein.
Oha, wo bleibt die #Aufschrei-Front
Bleibt die Frage: was ist "too much time" - Stunden, Tage, Wochen?
