Great shots, looks like you were pretty close.
Thank you.
I've worked out where they are in the park, so with a little patience, I just lean on a near by tree, then move closer bit by bit, and they kind of get use to you, I was about 15 foot away, and they was just running around in front of me.
lesson learnt today, check iso, I had the camera in manual mode, with the iso at 200, should have been about 400, as I had to do a bit of adjustment in lightroom., but pleased with how they turned out.
