Richard Kearton,
Nature's carol singers
(1906)
“ Why does a Skylark practise its notes on the ground more during the closing than the opening part of the season? How do birds know of a coming change in the weather and sing joyously to foretell it long before man, with all his acquired experience, is aware of the fact? Why do some winged melodists, such as the Blackbird for instance, sing the best during a shower of rain? Is it in anticipation of an increased supply of food? Would a chick that had never heard the song of its own species be able to sing it when it grew up? ”
