Birdies from today

Second time out since I got DA 300/4. First time wasn't very succeful as I was reluctant to use higher ISO than 800.
This time however I went really brave: auto ISO set to 4000, TAv mode with f7.1 and sutter at 1/640 or faster. All wit hHD converter.

Looks like ISO 4000 is fine on K3 II.

ALL C&C welcomed.

This one is fluffy so a bit softer, but still great
