I found them in the Angry Birds Evolution: The Flockers group, they were posted by Adam Kokoszko and Bob Morris.

Bob Morris posted it in November 25th 2017 and Adam Kokoszko posted it in February 16th 2018.

I found the other pictures in Angry Birds Nest but it's still mising a picture of Sidney's Face and some other.
