Merlin identifies birds as soon as it thinks it hears one; that is quite nice. I can click on the listed bird and it will jump to the section(s) of the recording where it heard the bird. Iirc birdnet makes you create a selection. I am no expert but they both seem accurate.
Yep, also need your pupillary distance. i havent gotten an exam in so long i cant remember if thats included in the prescript. Luckily my eyesight hasnt gotten worse (yet).
