I usually see my first hummer in early May, but one year had them on March 23 (I remember because it was Hubby's birthday). I set out one feeder last week thinking they might be sending their scouts to find the feeders. And I saw the first one this year last Tuesday, saw one, then on Wednesday saw two. Now I quess I need to set out more feeders to bring them in. But..... weatherman says we may see snow showers this weekend.
