Yesterday morning, whilst waiting for the Britomart train at Sunnyvale Railway Station in West Auckland, I noted a Kingfisher perched on one of the overhead electric cables. The Kingfisher was being mobbed by a Song Thrush with loud alarm calls & much wing flapping. Whilst this was happening, another Song Thrush appeared carrying an earthworm & flew down to the side of the rail tracks & attempted to feed a large & begging Song Thrush fledgling. Next the perched Kingfisher flew down to the Song Thrush fledgling & attempted to steal the earthworm now followed by two protesting adult Song Thrushes. By now there was much alarm calling & a second Kingfisher appeared, but I was unable to see whether the Kingfishers had snatched the earthworm from the Song Thrush fledgling. Unfortunately, my train then arrived & I was unable to observe any further action.
Just wondering whether anyone else has seen any similar interactions ?
It appeared that the Kingfishers intent was Kleptoparasitism rather than attempted predation of the Song Thrush fledgling, as the Song Thrush fledgling appeared larger than the Kingfisher !
