I have started to see a huge decrease of Orioles in my neighborhood in Green Mountain. Populations started to decrease with the increase of Coopers Hawk along the front range. Ten years ago, we had large numbers of Grackles, good numbers of Orioles, and more Robins in the neighborhood. The decrease in my opinion was caused by the spread of Eurasian Collared Doves throughout the country. Once they arrived, the Coopers Hawks soon followed with the large increase of food. It used to be rare to have a Coopers Hawk in the summer. During the winter months, it was Sharp-shinned hawks, which seemed to decrease also. The only increase has been the number of Black-chinned and Broad-tailed Hummingbirds. They are benefiting from the decreased number of predators like Blue Jays, Grackles, etc. who prey on their nest. Just my opinion...
