New Birds

I JUST SAW A HUMMINGBIRD! She was a ruby throated! And others (no pictures)....... American Redstart, Golden Winged Warbler, Canada Geese CHICKS (I've seen the geese, just not the chicks), Blue Headed Vireo, Wood Thrush (a month ago)......... Wow. That's actually not that much. Oh, but there's this one bird that I haven't seen but I hear it so much It's going to drive me CRAZY if I can't identify it soon! It's song sounds like "ChipChipChipZeeeeee." The whole song takes about four or five seconds. if anyone is a better birder than me (Which is likely), can someone tell me what it is!
