Strange Willow Warbler behaviour (1 Viewer)

Have just been watching a juv willow warbler around my parents bird table. It was seed eating on the floor amongst throngs of chaffinches, house and tree sparrows robins and dunnocks yet seemed unfazed. Later i went back to have a look and it was sharing the bird bath with a pair of great tits-on the floor this is not batting an eyelid? Is this exceptional behaviour-ive never seen these birds seed eating or in fact in the open!

Added to this i have just seen it hovering pallas's warbler style trying to take peanuts from the feeder. Strange
