Joe & Greg~ Congratulations on your county Big Day success. It sounds like you had a fun day. Although plentiful in numbers, I don't think a GREAT HORNED OWL (GHOW) is a big miss during May. Unless one flies across the road, is silently perched at dusk or is near a known nest, these birds are not actively calling or responding during this time of year. During 6 years of "Big Day" NAMC counting in Coos Bay, we recorded a GHOW twice and both were silent. I had this species nesting in my neighborhood every year and we still couldn't pull one out!! For my summer employment, I have been surveying ("hooting") for Spotted Owls since mid-April and have yet to record a GHOW this season. My point is don't feel too bad. :) Good birding,Russ NamitzMedford, OR
