...on the dimmer to a given luminance for 2 min. We found that activity threshold for secondary cavity nesting passerines ranged from 0.05 to 0.2 cdm-2 and non-cavity nesting passerines from 22.00 to 16.00 cdm-2. Our results shed light on the question about potential effect of luminance on visual performance by secondary cavity and non-cavity nesting passerines.
