Swamp birds.

All from 8/27 on the south side of Chicago.

1) Solitary Sandpiper?

2) Northern Shoveler?  I am judging this only on bill size.

3 )  Mallard to the left.  Wood duck below.  What is on the right?

4)  This sparrow was running between clumps of vegetation in the swamp.

Thanks.

1. Probably Solitary Sandpiper, but that tail barring really speaks to Spotted. Both have spots on back. Facial pattern makes it a prob Solitary.

2. Northern Shoveler. Nothing else with that profile.

3. Looks like Mallards in back. Wood Duck in front.

4. Odd sparrow. That is a crazy long tail. Has to be a trick of the eye, or weird angle or something. Any additional pic would help.

4 is Song.

I'm not sure that we can rule out Blue-winged Teal for number 2.

I agree with Blue-winged Teal on 2. Proportions are too stocky for Shoveler and the feathers by the base of the bill are pale. I think the bill is not as long as it appears in the picture and distortion is blending the bill with ripples on the water's surface.

The Sparrow is a juvenile, hence the odd plumage. Molted feathers around the rump of vent could contribute to the long-tailed appearance.

Yup, Blue-winged Teal.  Note the white tail on the right Mallard in the third pic.  Mallard and Northern Shoveler have the only wholly or nearly wholly white tails among dabblers; Blue-winged's (just barely notable in that pic) is fairly extensively white, particularly at certain times of year and more so in males than females.

Agreed

The shorebird's tail cannot be seen in the photo, and juvenile Spotted Sandpipers do not have spots, they have short bars, on their wing coverts.  Spotted also has short legs, and short wings, the tips of which do not reach the tail tip.  Finally, the site looks more like a marsh than a swamp. ?
