Yellow-chevroned parakeets are native to the tropical forests of South America, not neighborhoods in Southern California! But over time caged birds have been released or escaped forming self-sustaining populations in the Los Angeles basin. Like many other feral parrot species thriving in L.A., Yellow-chevroned parakeets feed mostly on exotic seeds, fruits, flower blossoms and nectar from non-native plants and trees.
Yes, the GNG still has some non-native plants on the property. But because these Australian silk oaks – Grevillea robusta offer so much to wildlife (we have seen over 40 species of birds use them in one way or another) it’s hard to consider the removal of these life-giving trees.
