No offense if you're a bird photographer

Haha!
"
On the trail" possibly means the other photographer was already interested in a subject and didn't want to be diverted, or didn't want to risk upsetting any potential subject

Unfortunately, no matter how quiet people are, two (or more) will always make more noise than one, so the potential disturbance to the local wildlife is increased.
Many outdoor photographers, by the very nature of their hobby, tend to be solitary, enjoying their own company … unfortunately these may feel uncomfortable in the presence of people they don't know, so do be prepared to respect their attitude.
Meeting up in bird hides is likely to be more profitable, if you've got such facilities in your area. The local wildlife is much less likely to be disturbed by people they can't see and other people using the hide can expect not to be alone

Alternatively, local scenic viewpoints, at an appropriate time of day, are likely to attract similar-minded people with a few minutes to spare.
