Interesting... Added side note, with an added side note...
The recent sightings ALMOST have me wanting to put up feeders for
hummers. But, I am really bad about keeping up with things and have
read, over the years, that it's important to maintain their feeders
well. I am not convinced that I would keep up with that faithfully so, I
have not put up hummingbird feeders over the years. I do have a wild
jungle of a yard that does seem to please at least a few ruby-throated...
But, I was just thinking yesterday... I wonder what the violetear's
favorite flowers are... and then, either planting them(or something
closely resembling it, or building feeders that look like it. That way
if any of those stray migrants wanders past my yard, it will be lured in
for my viewing. :)
Yes, I'm a dreamer. I know I'm not the only one though.
If I had more money, and a gardener, I'd be living in a pretty fantastic
yard... maybe some day.
