There is always one at the feeder that just does not want to share and this guy was it.
On our recent RV trip to western Colorado, I put out a feeder at our campsite and the hummingbirds provided the entertainment when we were hanging out. At times we would have four or five partaking in the treat but only until this guy showed up.
When he was around, he made sure no one got to eat except himself. If he wasn’t at the feeder, he oftentimes would stake out a spot in a nearby tree, keeping close watch and ready to dive in and chase off any others. Here, he hovers and checks the area before retreating.
