Observations were made at Ofu village, 20 km. south of Nagoya City. Alauda arvensis japonica can remain as resident in a field which, during the non-breeding season, becomes a wet paddy field.
It appears that the Lark can live in a field of 50, 000 to 70, 000 square metres. The density of population in this seasonally innundated ground is much the same as that found in the adjoining dry ground. It breeds 100 to 150 metres away from houses but, only 10 to 30 metres from the road. Acrocephalus arundinaceus orientalis usually breeds among reeds but if the reed no longer grows, the Great Reed-Warbler moves to nest in a nearby dry bamboo forest of 5 to 8 metres high.
