Rose Breasted Grosbeak Visits Habitat for First Time

Recently, I observed for the first time a rose-breasted grosbeak in the Colvin Run Habitat. The Habitat lies on the very southern border of the grosbeak's summer range.
During mating season, the male rose-breasted grosbeak takes on the rose colored patch on his chest. This male will spend 1/3 of the daytime incubating the eggs in the nest.
As you can see from the second photo, this grosbeak is about the size and from the same family as the cardinal.
I could not resist posting the last two photo showing a sparrow and cardinal, respectively, in flight and landing on the bird feeder.
