Kind of sounds like the Black-Capped Chickadee's ''Hey Sweetie'' song.  It can be found at http://identify.whatbird.com/obj/680/_/Black-capped_Chickadee.aspx

It's hard.  There are some Starling-proof suet feeders out there (look around with Google), but I have no personal experience.

Some Goldfinches just popped out of the nest.  Seems later than prior years.

Yeah -- at this point I think Catbird, Mockingbird, and House Finch are all possibilities.

Can you describe the sound at all?  Offhand, the Tufted Titmouse, Gray Catbird, and American Robin come to mind as possibilities.

I use one to prevent mosquitoes from laying eggs.  I'm sure it makes the water more visible to the birds as well, but the effect of this is hard to qualify.

I would imagine so, unless you're in Phoenix or something.  I've used numerous no-melt varieties here in Virginia and have never had one melt.

Great story. :-)

I gotta go with House.

Next guess is an Eastern Towhee.  Sometimes there's only one note before the trill rather than two.
