Teri,great pics,I did not see this thread before,don't know how I missed it
Yes,that is a Red Wing Black-bird,the others are Gold Finches as you probably know,I got lots of them too.
The bird in your snowpic is not a Junco,it looks like a brush Grosbeak,but I could be wrong,very pretty.
Juncos are sparrow-sized birds dark-grey and whitish,come around here only in winter.
