Jack Connor  > Murky Bird Pix > Orni 2013 Species To Recognize
Here are photos of the species to put on your "Should Be Able to ID" list. We have seen other species, but those included here are easily ID-able (from the readings) or have been seen well enough for everyone to have gotten a good look -- and then to study in the Sibley field guide. I've also added some questions to some of the photos to connect our observations with concepts and principles from our readings & discussions. How many of these species can you ID? How many captioned questions can you answer?. (This collection was last updated on 5-1-13.)

The answer to the question in caption under previous photo.
If you can ID this species, you know its Order from the reading -- and even if not, you can probably guess it from the posture (could a bird in any other Order cling to a leaf like this?).  What's the foraging method this bird is apparently using?
A member in the same Order as the previous several species (you can just see its back toe on right foot that's a good clue).  This species is in a Family you read about, many of which are "specialized to be generalists" (p. 412).  Which Family is that? This species is one of those "generalists":  note the bill which makes this bird a "jack of all trades."  Did you catch the box on page 409, pointing out that many of the species in this Family are omnivores?
Can you name the Order of this species?  (I hope so by this point!) Check out the toes and this strong grip.  In fact, this species' extremely strong toes and legs (and body balance) help place this species in its Family (the sub-category of Order).  Also, check out the bill -- shorter and thinner than the previous species but longer and more pointed than the conical bills of the more specialized seed-eaters (such as house sparrow, goldfinch, and junco). What can it do with that bill that other non-Family members cannot do?
By this time you are probably saying, "Please do not point out the feet tell the Order!  It's obvious!"  Ok, then, I'll ask you to note the bill. What could that be good for?
Remember the individuals of this species we saw on the Dark Path foraging like this? Remember the concept from the text about birds' "huge metabolic burdens" and the note that in winter white-crowned sparrows (this bird's closest relative) must find seed every four or five...(weeks? days? hours?).  We saw this bird finding seeds at the rate described. What was that rate?
Can you see the serrated bill that helps this species capture small, slippery fish?  Those serrations help to define this species sub-Family.
