Alberta follow-up to BC study (this one used many audio recorders in many habitats). In grasslands, nightjars avoid light, in boreal, don't seem to be as affected by it. Might be because there isn't true darkness in boreal forest in the summer b/c too far north.

Vocal pattern and temporal pattern isn't significantly affected by artificial light. But still need more investigation, back to BC or US?
