Derby Cathedral Peregrine Project: 3 weeks old








The 4 eyases decided they like the other side of the nestbox better. So they moved to stay.
But they did not know we can hardly see them overthere, but fortunately the project member changed the cam. Dear eyases now you can see how much we care for you all. Whatever you decide to do, the 4 of you, we will definitely follow....







The eldest eyases are stepping into their 4th week of development. Their weight is now more than 500 gram each. They are covered in white down, but we can see the retrices and remiges coming through very clearly now. The feathers are still protected by the shaft in which they grow. As we have seen, the chicks are able to walk now instead of moving around on their tarsi. Chicks always start to explore the immediate area around the scrape around this time. The parents stay around to watch the whole thing and to take care nothing happens. The chicks excersise their wings frequently to built up muscle power. They have to, the flight muscles need al lot of training to get strong enough to fly in 3 weeks. They are very communicative as well. They "talk" al lot to eachother and to the parents and have quite a rich language in sounds.
