One of the many exciting signs of spring is finding a Great Horned Owl on nest.  These Owls are among the earliest nesting birds in our area.  They usually lay eggs somewhere around Feb. 14 and the normal incubation period is approximately 28-30 days.  The female  performs the incubation duties in all kinds of crazy weather!  She may even be found covered with snow as she is most determined to protect her eggs!  Stay tuned as we monitor this nest in the Great Blue Heron rookery near the Methuen Rail Trail in Methuen over the next many weeks!!
