@Terry Thomas thanks Terry - it’s a great walkthrough area and an active group of small primates (along with Mara and Capybara) - it’s nice to be able to see them with no fence or glass in the way.
Great photo! Silvery Marmosets are an incredibly rare species for me, having seen them at only 5 zoos in my lifetime and none at all in North American collections.
@snowleopard Thanks, they are lovely and not all that common for me to see either, Banham was the first time I had seen them. It's been great to see a pair in an open walkthrough at YWP though - you get great views and can stay as long as you like just standing about watching them. I am a bit surprised they are not more common in the US.
