To begin with, fill your feeders with their favorite seeds. I have always provided the migrants with black oil sunflower seeds. They are also fond of safflower seeds and raw peanuts. While I have never served up either seed to northbound migrants, my daughter fills her feeders with both sunflower and safflower seeds. This year, the birds visiting her yard have shown a preference for safflower seeds. On the other hand, I have not seen a grosbeak in my yards this spring.
Saw one male this past Tuesday
I had three female and three male Rose-breasted Grosbeaks at my sunflower seed feeder yesterday. At one time there were three females and one male feeding off of the same feeder. That’s the most I have ever seen in my yard, ever. It has been awesome.
I have had males and females for the past week in Milledgeville. It’s always lovely to see them.
I’ve been seeing a few for the last week. Mostly males, but a female today. SW Gwinnett.
My grosebeaks showed up in Toccoa yesterday. The males hog the feeder and force/fight all the other birds inncluding female grosbeaks away until they are finished feeding.
