This is what I read in my Newspaper yesterday.There are a lot of PeFa's around Amsterdam.There is not enough place for them and they are even nesting in a working crane .Last year the nest failed ,but they made a nestbox on the crane and there is one chick this year, in the same area as the AEB  and the Hemwegcentrale (powerplant).
In the Hemwegcentrale is one male with two female'sThis is written by Paul Marcus.He is an expert on the PeFa's in Amsterdam and also he write's the weblog about The Mortel in Beleef De Lente.

He didn't expect this,but there are Three chicks in the nestbox.There is the adult female and there is a younger female.Unbelieveble isn,t it ?

That's interesting!  I know there are some birds that nest with two females in the same nest, read about that 2 years ago when I was first researching bigamous males but it was smaller birds they were talking about.  Can't remember which kind but was not a pefa.  I'd love to hear more about that!  I wonder if it's not a situation like Polly in Montreal or if this is tiercel really has 2 wives in the same nest...be a first for sure!!!

Carla, can we find out more information on it?

I allready have try to find out more,couldn't find it.I think about Tine from Amsterdam,she has had contacts earlyer about the A'dam PeFa's,she is a member on this forum too.

In the article I read that Paul has seen the male and the adult female so many times together that there was no sign of breeding .Still there are three chicks now.
I have send Tine a personal message.I hope she can help us.

This is the message I got from Tine,I don.t know how to translate it,but maybe you can with google on your own computer.


Paul Marcus is de kenner inderdaad en dat bericht kwam bij mij als volgt:
Via AmsterdamsVogelNet- AVN (yahoo)
"7 juni 2011: Gisteren zag ik dat er op de Hemweg twee slechtvalken waren
uitgevlogen. Vanochtend waren er drie. Ik weet niet of dat het volledige
gezin is. De valken zijn namelijk niet geringd. Medio maart leken de valken
te broeden, want ik zag een aflossing in de kast. Een dag of twee later
zaten er echter twee adulte valken, man/vrouw, constant in beeld. Dit
patroon herhaalde zich eenmaal. De ene keer vond er een aflossing plaats,
maar de weken daarop waren er steeds twee ontspannen valken buiten de kast
in beeld. Niets wees erop dat er nog werd gebroed.Op 15 mei 2011 zag ik het
mannetje op het uitvliegrooster zitten. Ik kon achter hem in de kast
duidelijk een al behoorlijk uit de kluiten gewassen jong zien flappen. Het
was duidelijk te laat om nog te ringen. Ik had al af en toe een vreemd
gekleurd wijf bij de Hemweg gezien, maar ik vermoedde dat er een komen en
gaan was van vreemde dames, die het broeden had verhinderd. Zaterdag een
week geleden was er een zeer vervuild en sleets overkomend wijf bij de
Hemweg. Vanochtend zaten er drie jongen op het dak van de gascentrale. Op de
dakrand aldaar bevond zich het schone wijf en hoog boven dit tafereel
troonde pa op de oostelijke hemelwaterafvoer van de westelijke schoorsteen.
Dat was om elf uur. Tien minuten later stond ik bij Bloms vatenhandel aan de
Van Riebeeckhavenweg en ik hoorde boven mij 'tsjik-tsjik'. Daar vlogen drie
adulte slechtvalken: Pa, het schone wijf en het smerige wijf. Laatstgenoemde
bracht een duif mee die ze afleverde bij de jongen op het dak. Ze bleef bij
de jongen zitten. Pa ging zitten op de camerabalk naast de kast en het
schone wijf ging achter een stel duiven aan.

Paul J. Marcus"
