Agree with Harry. And caution that even visiting a location may not result in detecting the bird. Even when one knows what to look and listen for. Louisiana’s have a loud, ringing song, but they do not sing constantly, and early in the season, they sing rather irregularly. For example, I took my son fishing at the Haw River last weekend. We fished at a known spot for LAWA. Did not hear or see one at all. We could say that they were not there yet, but would be wrong, as a friend had one at the same spot earlier in the day. The bird was no doubt there, just silent. The old adage that negative confirmation is not actual confirmation.

Subject: Re: Louisiana Waterthrush!
No, it is not early. Louisiana Waterthrushes normally arrive in the Triangle area between March 20-25. So, technically, March 28 is a tad late for them. I say, technically, because we would need to know how often you visit this site. If you visit it daily, or every two days, and this is the first day you have recorded it in 2018, then -- it IS late. However, if you visit this site once a week (or less often), say your last visit was March 21 and it was not there, it COULD have arrived March 22, 23, 24, etc., and been about right on time. But, March 28 is not early for this species.
For example, I saw and heard my first Blue-gray Gnatcatchers of 2018 this morning along Crabtree Creek in Raleigh. Compared with the last 5 years, that might be a tad late. But, I had not visited this particular stretch of greenway since February. Thus, the gnatcatchers could have arrived on March 15 or 25, and been early or right on time.

Singing here on the Little River near Hillsborough, NC today. Seems early for that?
