Hello all - which British and English folk songs feature birdsong prominently?

Three that spring easily to mind:

Pleasant and Delightful ('and the blackbirds and thrushes/sang on every green spray/ and the larks they sang melodious/ at the dawning of the day')

Down By the Green Groves ('it was there I did hear/the harmless birds sing/and you never heard so sweet/as the birds in the spring')

The Week Before Easter ('where the small birds are singing/and changing their notes/down among the wild beasts of the forest')


There are clearly many, many others - how many can we list? Do you have any personal favourites?
