Alice and I visited some friends who live in downtown Philadelphia, and I had part of a day to do some nearby birding. Brian Mohr and I went to the nearby John Heinz National Wildlife Refuge at Tinicum. This refuge spans Philadelphia and Delaware counties in Pennsylvania, and is adjacent to the Philadelphia International Airport. Established in 1972 as the Tinicum National Environmental Center, it was renamed in 1991 after the late H. John Heinz III who had helped preserve Tinicum Marsh. The refuge serves to protect the largest remaining freshwater tidal marsh in Pennsylvania; approximately 350 acres in size. When land acquisition is complete, the refuge will consist of 1200 acres of varied habitats.
I had targeted three avian species that had been seen there the previous week: two of which were potential life birds and the other was a species I wanted to photograph, but I didn't get to see any of them. However, we had a good four-hour hike where I saw 33 species, in addition to House Sparrows and Turkey Vultures seen outside the refuge. Other birders saw an Anhinga and a Sora there the same morning, but we did not.
There were lots of wading birds, ducks, and Double-crested Cormorants in the marsh.
Snowy Egret and American Black Ducks
Great Blue Heron and Bank(?) Swallow
Great Blue Heron and Wood Ducks
Great Blue Heron, Canada Geese, Wood Ducks, and Blue-winged Teals
One of the two Teals next to the Great Blue Heron has quite a bit of rust coloring. I wonder if it might be a Cinnamon Teal or a hybrid Teal??

The only sandpiper species I saw there was Lesser Yellowlegs, and there was a good sized flock of them.
Two Marsh Wrens were near the marsh, but neither of them wanted their picture taken.
The rufuge had several miles of wooded trails around the marsh areas. Gray Catbirds seemed to be everywhere.

One of the wooded tails along the marsh had a good number of warblers. Most of them were Palm Warblers along with several Common Yellowthroats. In the field, I thought that I had seen both Waterthrush species, but after carefully examining the photos, I think that both birds were Northern Waterthrushes.
Most of the wildlife seemed to get along well with other species at the refuge.
