A Great Horned Owl is nesting nearby in the Nevins Bird Sanctuary in Methuen.  It most likely laid eggs in the last week or two.  Typically the GHO will lay a total of two eggs although they may sometimes lay up to four eggs.  Then the female GHO will incubate the eggs for about 30 days.  The female stays on the nest through even the roughest of weather until her incubation work is complete.  She may even be observed covered in snow, but no matter what the weather, she remains on her nest for the duration!  Stay posted for further developments and hopes that eggs will hatch by the middle of March!
