Thanks for playing along with my latest birding quiz posted yesterday.
Here’s the answer … it’s a
female Rose-breasted Grosbeak.
I told you it looked nothing like its male counterpart (in color anyway).
I also suggested you look at the “bulky bill,” or in this case its “grosbeak.”
Many field guides show only the male in breeding plumage, therefore making the identification of females or nonbreeding birds nearly impossible. Get a good field guide that shows all the various plumages of birds.
Below is the male Rose-breasted Grosbeak striking a similar pose. Quite a difference, huh. Good example of sexual dimorphism (when males and female have different physical characteristics.)

Sexual Dimorphism in birds is certainly a sore blow to feminists!

I had one at the feeder outside thr window on the porch…I thought it was a Grosbeak because of the shape of its beak thanks to your post I discovered it was a female …I had never had one visit before. It just sat and had snack, looking around totally unfazed by my presence … Fascinating ,!
