Field Marks and
Identifying Characteristics:
I saw this bird rummaging in the debris on the shore. I could tell right away it was a RUTU by the coloration and markings on the chest. It was in breeding plumage. The bird's back was orange/rusty and black and the head was black and white with a distinct black pattern on the chest, and it had very orange legs when you got a glimpse. It was much smaller size wise than the Willet and Avocets near it, and larger than the Spotted Sandpipers that were near. We all got a good look at it from about 200 ft away, then we moved closer to it about 100 ft or closer.
(see photos)
Song or call & method of delivery: None made
Behavior: It was rummaging in a debris pile (of brine fly casings, sticks, and whatever else), tossing the debris up in the air.
Habitat: Shoreline, mudflat on northwest side of Lee Creek delta
Similar species and how
were they eliminated:
The most other similar species, in breeding plumage, is the Dunlin. Our bird did not have a black belly, and the Dunlin has a much longer bill and no facial or check markings. Another slight possibility due to shape and size is the Black Turnstone, but our bird was rusty orange instead of all black. Another possibility could be the Surfbird as that bird has some orange and black on the back, but the color intensity is much less, and the face and chest markings are not distinct.
Previous experience with
this & similar species:
Earlier this year and last year on the causeway. Many in Texas in the past 2 years, most recent in April 2025.
