This Warbler was trying to steal the Humming Bird Nectar-lol 🙂
The orange-crowned warbler has olive-grey upperparts, yellowish underparts with faint streaking and a thin pointed bill. It has a faint line over each eye and a faint broken eye ring. The orange patch on the crown is usually not visible. Females and immatures are duller in color than males. Orange-crowned warblers are distinguished by their lack of wing bars, streaking on the underparts, strong face marking or bright coloring.
