(Phylloscopus trochilus)
A friend called to say that he had a warbler's nest in the garden and I found that the birds made a habit of landing on this foxglove stem on their way to and from that nest.
Further watching revealed something very unusual. The young warblers, which were only two or three days old, also had a foster parent. A Robin (Erithacus rubecula) was trying to feed the nestlings without success - it was bringing to the nest worms rather than insects!
