This fella can barely squeeze through this crack but is content none the less. I walk on this slab of rock all the time-- there are several lizards that spend most of the winter under it. Hope it don't shift one day!! It's been sunny & warm for a couple of days--- I have seen all 11 baby chucks & plenty of Yarrows. The young redtail female "Tur Golinka" also took to sunning--firtst emergence in months. No adults seen so far.
