the HABITATS The Spillway/Fish
Hatchery
The Spillway/Fish Hatchery
Area is a dam spillway adjoined by a few acres of bottomland habitat. The
bottomland area contains man-made fish ponds overgrown with a dense shrub component
and some older hardwoods (hackberry, pecan, willow and oak trees). Several
trails wind throughout the small woodland. The habitat here is
particularly diverse and maintains the broadest selection of birds around The spillway itself is a
very good place to look for sandpipers in migration and gulls in winter. A
wide variety of ducks and occasionally pelicans can usually be found by
walking the area just above the dam.

Out of range birds or unexpected birds with few
known records. Western Grebe (1 record) Ross’s Goose (2 reports
presumed to be wild birds) Black-necked Stilt (1
record) Jaeger sp. (1 record) Mew Gull x (possibly
hybrid) Glaucous Gull (at least 1 record) Thayer’s Gull (at least 4
records) California Gull (at least 4
records) Least Tern (pair, 1 record) Black-legged Kittiwake (1 record) Whip-poor-will (1 recent record) Black-chinned Hummingbird
(1 record) Acadian Flycatcher (1 record) Lazuli Bunting (1 record) Western Tanager (2 records) Small Flycatchers at White Rock: Chris Runk recently did an
informal study of the hard-to-identify Traill’s complex of empidonax
flycatchers around White Rock Lake. Over several years, Chris visually
identified 25 birds that fell into the Traill’s complex (Willow or Alder
flycatcher). Of the ones that called, 17 birds were Alder, 2 birds were
Willow, and 6 birds were silent and remained unidentified as to species.
Willow is an early fall migrant in Dallas and of the few empids that can be
identified in July, most are Willow. Most other small eastern empid flycatchers can be identified visually, but it’s frequently difficult to get an adequate look. Call and song are still preferred as ID characteristics, particularly in Texas where a western empid is still quite possible. Most empids in Dallas Co., are May migrants in spring, but an unusual Yellow-bellied Flycatcher in June is still possible as this species can sometimes be quite late. Acadian Flycatchers might be possible as early as April, but this flycatcher, common to the southern bottomlands, has never been particularly common in Dallas County even though it nests only about 100 miles to the south and east. Most small flycatchers stretch out their fall migration through August and September.
