Orchards in Okanagan suffered severely from an attack of locusts 

 during 1914, Melanoplus qffinis and M. femur-ruhrum being the most 

 abundant. Orchards in which clean cultivation was practised were 

 most seriously damaged. Clover, lucerne and hay-crops were also 

 attacked. The outbreak may be attributed to the abnormally hot 

 and dry season experienced, the influx of settlers and the consequent 

 diminution of the natural food of locusts, and too heavy or 

 injudicious grazing, which has destroyed the natural food-plants. 

 The egg-masses are devoured by several species of blister-beetles, 

 notably Cantharis cyanipenms. From previous records, severe 

 outbreaks appear to occur every seven years.

This paper gives an account of fifteen species of birds occurring in 

 the Nicola Valley. The food of these species consists largely of grass- 

 hoppers, these in some cases forming 42 per cent, of the total.
