Cooper is quite right, first bird came in at about 12noon and had a quick look around and then later in the afternoon there were two birds - looked like one female and one male.

Male does look like Ivy but he wasn't staying still long enough for me to get a look at his legband. The coloured band is on his right leg which is the "right" leg for Ivy, but also for Beau for that matter.

As for the other bird, looked larger and was very leery of the outside-box cam which is something Princess is not. Also the bird's breast is white, not like Princess at all. Couldn't get any kind of look at that bird's legbands. Could be Sandy, could be Jules ...
Going to post some video on the Project's YouTube Gallery and you can look for yourselves.
