Nightingale sp., early song, 8 Apr in Warsaw, PL (1 Viewer)

[01101001]

I presume Thrush Nightingale due to the dry rattles, unfinished and distorted whistling phrases (mixed singing), short phrases with long breaks (only the beginning of the season), and either sharp or buzzy vertical notes appearing in mid-frequencies at the end of many phrases.

Can we age the bird as an adult based on the stage of its vocal development (I've heard much plainer song devoid of mixed singing a month after April 8)?

I’ve not heard Thrush Nightingale 01, however to my ear it sounds like Common Nightingale, others may differ? 👍

It's a Common Nightingale varying a bit. Not full song of an established individual but still on migration.

Indeed, the rattles at 0:12, 4:26 and 5:28 sound too soft for Thrush Nightingale, I think. What about the one at 6:26, though -- it's rougher but probably too short?

As it's probably a Common Nightingale indeed, interesting how -- at the beginning of the season -- it sounds like Thrush Nightingale towards the end of the season with regard to the development of the whistled phrases (I guess Common Nightingales would've started learning them earlier, obviously, but -- otherwise -- the outcomes of both species' learning processes seem broadly similar).

EDIT: What other criteria have you used (provided that they are easily describable) to help differentiate between the two?

(Just to dispel any doubt, Common Nightingale is more probable and, also, favoured by BirdNET (I've checked with it afterwards).)
