The Whaa's new Spring joke

Yellow everywhere!

The Whaa's new joke: "What is yellow and swings from cake to cake ?"   
(Brace yourself!) ..."Tarzipan"!   (BAD)Yellow jokes.  Yellow Sun. Yellow flowers. Even the birds are turning yellow.

The Wagtail
The yellow wagtail is a small graceful yellow and green bird, with a medium-length tail, and slender black legs. It spends much time walking or running on the ground. As its name implies, it wags its tail from time to time. It is a summer visitor, migrating to winter in Africa. It has been in decline since at least the 1980s, most likely due to loss of habitat for breeding and feeding, making it an Red List species.

Yellow Hammer:
Males are unmistakeable with a bright yellow head and underparts, brown back streaked with black, and chestnut rump. In flight it shows white outer tail feathers. Often seen perched on top of a hedge or bush, singing. Its recent population decline make it a Red List species.
