The scientific name Asio grammicus is not widely recognized for a currently living bird species in mainstream ornithological lists. Information provided here is generalized for owls in the genus Asio, which are typically found in various habitats globally and known for their prominent ear tufts.
Where to spot
As a general Asio owl, expect to find it in diverse habitats ranging from open grasslands, marshes, and agricultural fields to woodlands and forests, often near suitable hunting grounds.
How to spot
Look for characteristic ear tufts (though not always visible in all species or when relaxed). Listen for their varied hoots, barks, or hisses. Scan open fields or forest edges, especially at dawn/dusk, or look for roosting aggregations in dense trees during the day.
When to spot
Most Asio owls are nocturnal, active from dusk through dawn. Some species, like the Short-eared Owl, are also active during the day, especially in winter or during migration.
