Had a long look back through the recordings and had a very early morning visit by a bird with a black head and very nice broad white breast - Ty and Hart are our only boys with that and Ty doesn't seem to stray from West Winnipeg and this bird looked particularly familiar and comfortable where he was, so it it was anyone it would have been Hart.
Joli was around yesterday at an odd hour of the afternoon (odd for her at least) doing a lot of preening by the nestbox. Couldn't read her band number but her coloured band is on the opposite leg from Hart's.
