Great Fall Migration Showing

Steven McDonald and I both coincidentally arrived at the Braes Valley parking lot of Lake Creek Trail at about 9:00 this morning. We then spent over three hours on the trail and enjoyed a cool overcast morning full of fall migrating birds. Baltimore Orioles were nearly ubiquitous between the parking lot and the footbridge. We estimated there were at least 50 of these black and orange birds in the woods along the trail. We found 5 species of flycatchers, including brief appearances by both a Yellow-bellied Flycatcher and Olive-sided Flycatcher. Vireos included White-eyed, Bell's, my first Blue-headed of the season, and this Warbling Vireo:

Other south-bound songbirds we found included Yellow Warblers, Wilson's Warblers, a single Black-throated Green Warbler, and at least one Blue Grosbeak. Tightly grouped starlings helped me notice a juvenile Cooper's Hawk perched on a light post in the Town and Country playing fields. And a migrating Northern Harrier flew over the footbridge while we made our way back to the trail head. Here's our complete bird list. What a morning!

Birding on Broadmeade Walk

This morning's group walk was the best in years! The weather was cool, overcast, and breezy, and south-bound migrating birds were out in force. Fourteen people enjoyed over three hours on the trail and we totaled up 44 species of birds, including a couple unexpected rarities. We met at the Parmer Village pond, and just as we were starting this juvenile Little Blue Heron flew in and started hunting on our edge of the pond:

We made our way upstream by the creek bed and things were pretty quiet until we got close to the last dam. Further down the trail I started seeing Baltimore Orioles flying out of the woods, and we stopped to watch them.

Labor Day Weekend Birding

I spent about three hours on Lake Creek Trail on Sunday morning, hoping to see some birds heading south. Starting at the Braes Valley parking lot, I was a little surprised that the woods between there and the footbridge were pretty quiet. I made my way to the eastern most low water crossing on the creek bed before turning around. On my way I noted higher numbers of Killdeer (our year-round residents are joined by south-bound migrants right now) and a few Least Sandpipers in the creek bed.

I was hanging around a little downstream of the last low water crossing when I spotted a few Mississippi Kites in the sky. These migratory hawks are extremely elegant fliers with long pointed wings and long tails. They often catch dragonflies out of the sky, and when they migrate it is often in large groups. The group I was watching turned out to have 36 birds, and here are 14 of them:

It turns out that two other Austin-area birders saw larger groups of Mississippi Kites on the same morning. Weather conditions must have been good for them to travel!

On my way back I found a few more cool migrating birds in the creek bed.

Birding on Broadmeade Walk

Eight folks got up early and enjoyed an unseasonably cool morning with me on Lake Creek Trail. Things started a bit slow but we observed 36 species during the almost three hours we spent on the trail.  August is an interesting time to look for birds. Many birds are molting and can have unusual appearances, south-bound migration has started, and even non-migratory species can be wandering outside of their usual ranges. We found examples of all three of these phenomena this morning. An early highlight was briefly hearing a an Upland Sandpiper fly overhead, a southbound migrating shorebird that uses grassland habitat. This time of year they can be heard flying over in the mornings and evenings if you know what to listen for.

From the footbridge we got to see a male Northern Cardinal that had molted all but one of its crest feathers. Despite its weird appearance, it sang from an obvious perch as usual. Here's a photo:

Molting is a major yearly event that birds usually experience after breeding in late summer. Northern Cardinal is the only species I know of that often loses all of its head feathers at once during its molt.

Least Sandpipers

I spent some time on Lake Creek Trail yesterday early afternoon counting dragonflies, and hoping to see a Couch's Kingbird that Barry Noret found there that morning. I missed the kingbird but enjoyed finding 18 species of dragonflies. (I posted a few photos here.) Dragonflies are a new interest of mine, and I've been enjoying learning how to identify them and being able to contribute to the Migratory Dragonfly Partnership's Pond Watch citizen science project. Despite primarily observing dragonflies, I kept a bird list too which ended up with 27 species.

I was most excited to find a group of 32 Least Sandpipers on the creek in the middle of Town and Country playing fields. These tiny migratory shorebirds breed in Alaska and northern Canada, but they can be found in the Austin area during every month of the year! Why is that? The northern edge of their winter range includes most of Texas, so many make the Austin area (including our little creek) their winter home. And the population is so wide-ranging that shortly after the last spring migrants move through central Texas in mid-June, early south-bound migrants begin to appear in early July. The birds I saw yesterday were some of these early south-bound migrants. Here are a few of them:

Least Sandpipers


In my early days of birding I was amazed that sandpipers could be found in Austin. It continues to amaze me that our neighborhood creek is so important to many of them as a winter home and a migration rest-stop.

Birding on Broadmeade Walk

Eight folks joined me this morning for the monthly group walk. We met in front of the Parmer Village pond and I photographed this Scissor-tailed Flycatcher while I waited for people to arrive.

Scissor-tailed Flycatcher

It was a fun morning! We ended up spending two and a half hours on the trail and recorded 35 species of birds. By the creek bed near the pond we enjoyed watching Western Kingbirds and Scissor-tailed Flycatchers chasing insects and themselves. As we made our way upstream we heard a Red-shouldered Hawk vocalizing but only got brief looks at it as it flew over the treetops. We also saw four American Crows react to its calls and briefly chase the hawk. As usual, when we reached the last dam on the creek we waited there awhile to see what might show up.

Bird-A-Thon!

I led a short version of a Bird-A-Thon this morning on Lake Creek Trail for our local Travis Audubon Society. Six of us met at 7:30 AM at the west end of the trail and we spent the entire morning walking its 2.4 miles and seeing how many species of birds we could observe. We recorded 59 species! Here are some highlights.

We got to briefly see and hear a singing Brown Thrasher (probably the same bird observed on the last group bird walk). A Bronzed Cowbird made a brief appearance just beyond the footbridge. While we stood next to the creek bed we got great close looks at a Yellow-crowned Night-Heron and two similar migrating shorebird species: Solitary Sandpiper and Lesser Yellowlegs. Here are the shorebirds, both only seen here during migration. First the Solitary Sandpiper:

Then the Lesser Yellowlegs (one of the four that flew in while we stood there):
