Welcome to the Alberta Nocturnal Owl Survey Data Entry Page

In the past few decades there has been increasing concern over the status of both diurnal and nocturnal raptors.  Their position high on the food chain makes them vulnerable to many environmental disturbances.  As such, they may be valuable indicators of environmental health and many species of raptors have been chosen as indicator species. Relatively little is known about the abundance and population trends of most species of nocturnal owls in Alberta.  Most owls are not adequately monitored by the existing continent-wide surveys in North America.  
 
Alberta’s volunteer Nocturnal Owl Survey was initiated in 1998 and became a full-time program in 2002.  It is coordinated by STRIX Ecological Consulting and over 200 people participate across Alberta!!
