Can we talk about my near-miss with a hawk nest during a removal?
I was removing a silver maple and didn't check the canopy properly. Halfway up, I spotted a red-tailed hawk nest with young birds. Had to stop immediately and contact wildlife services. It was a wake-up call to always inspect for wildlife, even on jobs that seem routine.
Spent ten minutes scanning a big elm with binoculars before climbing. Saw a pair of owlets tucked in a crook I would have missed. Now I make it a rule to do that scan in the morning light when birds are active. It adds maybe fifteen minutes to the setup, but it saves a lot of trouble later. That habit caught a nesting coopers hawk just last week.
What @mason765 said about scanning first really hits home. In my experience, that kind of pause to look around saves headaches in all sorts of jobs, not just tree work.
Last spring, I almost took out a squirrel drey in an oak tree because I was in a hurry. My crew still gives me grief about it, calling me the "wildlife wrecker". I was so focused on the cut that I missed the chewed branches and nesting material. Now I do a full walk-around with binoculars, even if it adds time to the job.
