Brown Creeper, disappearing.
Were it not for their predictable habit of hanging out in the trees surrounding the Sandy Hook Bird Observatory and climbing upwards (but only partway!) before swooping down to the base of a nearby tree and starting their ascent all over again, I’d probably never notice them.
I did spend all that time watching kinglets yesterday tho, so my eyes had plenty of time to wander to the other birds who keep company with them.
Brown Creepers don’t look like much, but they’re a treat anyway and their song is sweet beyond words.
Where must a person live to hear Creepers sing regularly?
