The other day during fall migration, I added the 92nd bird to my yard list: a Palm Warbler. It was a quick visit - probably less than a minute, but the bird exhibited some of the key behaviors that help identify it as a palm: found on or near the ground and a steady pumping of the tail.
This was my second new yard bird this year, the other being a Field Sparrow that passed through during spring migration. The last two years, I've added three new birds each year, so I'm hoping to keep pace by adding at least one more new bird.
Now is the best time to do it, with fall migration in progress. But it's also one of the harder times, with all the "confusing fall warblers" that test even good birders' identification skills.
