Ibis

I spent most of this morning birding the eastern part of Lake Creek Trail, starting at the Parmer Village pond and working my way upstream. Near the last dam I was excited to find a dark ibis. It was far away and I couldn't see much detail, but I think it's a juvenile White-faced Ibis which is the more common dark ibis here. It can be found in central Texas in small numbers most of the year, but is more common during spring and fall migration. It flew further upstream and almost out of sight before I could get any photos of it. It flapped periodically as it foraged, which I could still see in the distance.

Later I was able to find the bird again and approach it much closer. It was still flapping periodically and now I could see why. This bird was missing most of its right lower leg. Every time it started to take a step with its right leg it would flap its wings and hop on its left leg instead. A few inches of bare bone protruded below the swollen knee. This must have been a dramatic injury! Here is a reminder of what tough lives wild animals lead. Who knows what kind of situation caused this injury and how the bird escaped it. And there is no way for the bird to tell its story. It goes on with the priorities of life because it still can. And as long as it can still fly and the injury isn't infected, it has a good chance of surviving for many years. I hope this bird's remaining years are easier than its first!

Birding on Broadmeade Walk

This morning 12 folks participated in this month's group bird walk. We started at the Braes Valley parking lot and spent about 2.5 hours finding 31 species of birds. The previous day's north winds supported an amazing flight of hawks over the neighborhood. (Here are some photos.) But this morning's winds were back to the usual southeast with overcast skies. We didn't see any migrating hawks, and things started out quite slow. But we ended up making a few exciting observations.

For the first half hour or so the birds were quiet. I was desperate to have something interesting to show the group when I spotted this Praying Mantis hanging upside-down on a ragweed plant:

Things finally started picking up as we approached the footbridge.

House Wren

Just a quick note. Here's a House Wren I found on Lake Creek Trail this morning. House Wrens are winter residents of our neighborhood, and this was the first one I've seen this season. It could be on its way further south or it could be here to stay until the spring. First I heard it scolding, and I flushed it out of some tall grass into a dense thicket of poison ivy and grape vine. Then I coaxed it to the edge of the thicket to have another look at me by playing recorded House Wren scold notes on my iPhone.

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.
