I was told that by Penny ( the woman who imports animals for Chester), that she was from Bronx. This would also fit in with ISIS.
Update on Chester Red BoPs: They are now mixed with a flock of Mindanao bleeding hearts (Gallicumba Criniger). This seems to be working well. The BoP aviary, is much better than the pigeons previous aviary. It seems to stimulate foraging.
There is, or was, a male Palawan peacock pheasant in the back BoP aviary, but he may have moved to the main pigeon aviary, as I saw a sign there. The odd thing about him is that there was no easy way of being able to see him. He would always skulk about on the floor, and as the back aviary is only just on view, being able to see him, was difficult. I have no pictures or film of him. The zoo also has a pair of Palawan Peacock Pheasants in the bird corridor.
The two male chicks, have now got the beautiful green feathers on their head. One of them, is very tame, and used to live in the tropical realm with a pair of malay crestless fireback. He will still come up to the aviary and start chirping. The two chicks are not fully grown, as they do not posess the red tail streamers.
All three male BoPs at Chester zoo are living together. I have not Knowingly seen the female. I may have mistaken her for one of the chicks earlier on in the year, but I'm not sure.
