Early Return

Rufous Hummingbirds often return on the same day of the year from the south.  This spring one of them returned on March 4, which is about 10 days earlier than last year.  Is it the same one who just made an earlier arrival?  Or is it another individual who arrived here early?

"Hi, I am a male Rufous with the brown back.  

After some rest, I will take off to travel further north."

I was expecting the Rufous arriving soon and just the other day replenished the sugar juice with the new batch.

"I found your sugar juice fresh.  I will come back while I am around."
