[Tweeters] When Merlin Won't "Hear"

[Jerry Tangren via Tweeters]

Merlin has an obvious problem on my iPhone, especially after a period of sustained use, 20 minutes or so. It becomes mostly deaf, but not entirely.

My guess is that it’s associated with memory use. The iPhone dynamically assigns memory to Merlin while the app is running. It appears that after time, Merlin is floundering in its memory use.

It appears that if you close Merlin, the iPhone or the app is able to recycle the wasted memory. If you then open Merlin it can again id bird sounds. I’m not sure how long the process takes, but it’s at least a few minutes.

I first noticed it this last May when we were birding Cuyahoga National Park near Cleveland. We are less familiar with the eastern birds so for periods of time we just left it running. It detected a remarkable number of species we might have otherwise ignored.
However, we did not count the species unless we could confirm them ourselves.

If you’re interested my trip list is on eBird at

Several times Merlin has failed to acknowledge a bird call that seems clear to me. In those cases, when I get home, I play back that Merlin record to another birdsong app, BirdNET. This free app is also Cornell-scientist designed. One plays the bird song with Merlin, highlights the resulting sonogram on the BirdNET app, then hits "Identify." Often a correct ID will result.
