Which is correct?

Harris's Sparrow, Harris' Sparrow, or Harris Sparrow?
"We are as often injured as benefited by our systems, for, to speak the truth, no human system is a true one, and a name is at most a mere convenience and carries no information with it. As soon as I begin to be aware of the life of any creature, I at once forget its name. To know the names of creatures is only a convenience to us at first, but so soon as we have learned to distinguish them, the sooner we forget their names the better, so far as any true appreciation of them is concerned."
- Henry David Thoreau
Do you agree with Thoreau?

Garlic Mustard

Garlic Mustard
Every spring I observe birders with good intentions pull Garlic Mustard (Alliaria petiolata) at Pheasant Branch Conservancy, but then leave piles of the invasive plant along the trail. This is a particularly nasty and resilient plant and to say that garlic mustard is prolific along the corridor trail is an understatement. If you're going to pull the plants, please bag and remove them from the conservancy – do not simply leave them lying on the ground. Plants that are pulled and left behind may still set seed and by doing so you may be unwittingly contributing to the garlic mustard infestation along the stream corridor.

One of the many Garlic Mustard Gardens at Pheasant Branch
When it rains, running water may wash the pulled plants (or seeds) off the gravel trail back to the soil. Also, not everybody who walks the trail knows what these piles of plants are and may kick them off the trail. With hundreds of thousands (probably millions) of garlic mustard plants, pulling a few dozen of them isn't going to dent the problem. But those who are pulling the plants out by the hundreds should plan on bringing bags and carrying them out of the corridor.

These plants might wash into the stream next rainfall.

No Border Wall

As many other birder bloggers are doing, I'm posting about the completely asinine Texas Border Wall our federal government plans to install along the Rio Grande River. In the process, they're going to severely compromise and destroy sensitive habitat, and literally hand Sabal Palm Sanctuary over to Mexico. Many other natural areas and wildlife in the region will be adversely impacted and you can read about the whole awful mess at No Border Wall website and blog. It may be too late to do anything about it, but there is now an on-line petition you can sign to express disapproval of the planned destruction.

May 1st Field Trip Results!
Participants of this morning's Madison Audubon field trip at Pheasant Branch were thrilled to see a beautiful male Cerulean Warbler foraging low. We had 9 other warbler species this morning, including Blue-winged Warbler, Black-and-white Warbler, Tennessee Warbler, Nashville Warbler, Golden-winged Warbler (sang later), and both waterthrush species. Thanks to all who attended and helped make it a special day!
Here's a frame/screen capture last night's bird migration on NexRad:
