OK, they are probably not really siblings, but these two Canada Geese goslings (Branta canadensis) were walking around the local Idaho park grounds together and they suddenly started "yelling" at each other. They reminded me of my brother and sister getting into it with each other when we were kids...so the title fits :)
Most people photograph geese gliding. You waited for the argument. That's a better photograph.
Gosling standoffs are the best. I spent a whole spring morning once watching a family group near the Shenandoah and the young ones had this exact energy, beaks open, full volume, total drama over nothing. That sibling title is spot on too, mine used to sound about like that at the dinner table.
The title is spot-on. Nature photography at its most charming and candid way!
Thank you!
