How many breeds of birds fit on a tree?

There are two types of birdwatching. The classic one is where you go and seek out the birds. A much easier one is where you stay put and let the birds come to you. During a June trip to Lake Nockamixon, we parked ourselves near a tree with ripe berries, and for an hour successfully indulged in birdwatching type #2.

So how many breeds of birds fit on (and around) a single tree? I am going to count them:

1. Red-bellied Woodpecker


This one is also a red-bellied woodpecker, but it's a juvenile:


2. Baltimore Oriole:


3. Song sparrow:


4. Downy Woodpecker:


 5. American Goldfinch:


6. Eastern Kingbird (taking an insect to its nest):

7. Northern Cardinal:


8. Wood Duck:


9. American Coot:


10. Eastern Bluebird:


11: Killdeer:


12. Don't know what this one is, but it was there too:


Not bad for a single tree spot!
