Great Horned Owl

https://faunafocus.com/home/august-2017/#jp-carousel-2534

Great horned owls are not regarded as migratory, as they do not make regular seasonal journeys between breeding and wintering grounds.

In winter, great horned owls often leave regions where suitable food is scarce. Probably, there is some migration of these birds every year from the northern parts of their range toward more southern regions. In some seasons of scarcity, this migration increases to considerable proportions. The spring migration northward is not so evident as the fall exodus.

They are not always successful in this migratory search, however, and now and then, one is found starved and frozen in the snow. Such specimens, when discovered, are very much emaciated.
