I visited Phoenix, AZ recently. I stayed at a beautiful place at the foot of South Mountain. The place had a patio that overlooked the city and at the corner of that patio was a large saguaro cactus. The mornings were beautiful, so I sat on the deck and watched the birds as they visited the cactus. Here is some of what I saw.
The starling was not taken on the same cactus. It was sitting outside its nesting hole on a cactus at another location.
