Bird activity level and species present at a given latitude are affected by light levels or what is called photo-periodicity. The current light levels of autumn are similar to spring light levels, and as a result, Merlinsoverwintering in breeding territories are actively courting. You can hear them emphatically “chittering” their call (like Douglas Squirrels) in conifer tree tops close to their activity trees. The male will fly in a “slow-flutter” display close to the nest platforms and attempt to attract a female by this activity and also, the presentation of a prey item.
Listen to them, and enjoy the marvel of nature and share your citizen sightings with the Merlin Falcon Foundation: merlinology@hotmail.com
