Oberhausen
Sadly all 3 cams are down. Not the right moment to shut down, after the female has laid her first egg yesterday. We all would love to see her now. Hope they will repair the cams very soon! I will keep you updated.

Ain't she pretty??
Oh so pretty....
The courtship phase has now begun, although it does seem to involve a lot of standing around in het nest , or at the ledge.The daily phase of hesd bowing low usually begins with the male standing in the nest scrape that he has made. The female peregrine arrives with loud and repeated "ee-chupp" calls. With his head down, the male remains static for four or five minutes, stared at by the larger female on the far side of the nest ledge. Almost looking as if his nerve suddenly gives out, he flies off, leaving the female alone. A minute or two may pass before she plods over and stands in the empty nest scrape. Turning a few times, she may also give a few scrapes at the gravel herself, before eventually moving to the edge of the ledge where she may remain for some time.

Bologna: Felix & Aisha
Aisha spents a lot of time in the nest. That's a sign of ovocytes riping out in her ovaries. Her hormone levels ar every high. This makes her preparing for laying the eggs and breeding.Zurich
This doesn't look to comfortable. I keep thinking, what happens when it starts to rain. Or when the hot sun is shining? No protection at all. Well we just have to wait and see. For now they are courting. He is offering her prey, as he should do this time of year .....
Am 92 Meter hohen Kamin des Kehrichtheizkraftwerkes (KHKW) Josefstrasse ist seit einigen Jahren ein Nistkasten für Turm- oder Wanderfalken eingerichtet. Im Jahr 2003 installierte Grün Stadt Zürich in Zusammenarbeit mit Orniplan und ERZ eine Kamera am Kamin des KHKW. Die Kamera ist auf das Anflugbrett vor dem Nistkasten gerichtet und zeichnet die Falkenaktivitäten auf.

Oberhausen, first egg of the season.
She is showing us her egg, that was laid this morning. In the past day we have seen many copulations, and on this day she started egglaying.
She will go on laying an egg now every 52-54 hours. That's an average. Some females take more time in between egg laying. Mariah of Rochester even took 103 hours between her 5th and 6th egg in 2006. But that's very exceptional.

Both at the nestsite head-bow-low. And probably ee-chupping. I expect the female starting to lay eggs any day now.
