LOL, that’s hilarious. OP has not relinquished their copyright, and are fully able to issue a DMCA takedown. Doesn’t matter that he supplied the pics to the band, he’s still in full control of the photo. Furthermore, when he supplied the pic, it was with the express condition he be cited for his work, he was not thus…he’s fully within his rights as owner to pull them back.

Daylight generally provides enough light for the job.
Additionally, depending upon the animal you’re taking pictures of, shutter speed likely doesn’t need to be above 1000/1500. Most animals are not moving around at full speed all the time.
For birds in flight even, I shoot around 1/1250 or so. Exceptions would be hummingbirds if I want to stop wing movement, that’s at least 1/2500 or a bit higher.
And equipment can make a big difference. For serious professional shooters, they may have a fixed aperture of say f/4 or f/5.6, which is excellent. A budget lens can be several stops more which would cause challenges, particularly at dusk/daybreak.
