Well, if you didnt see the horses then i guess you must have missed them. As for the guys with rifles, iv seen them a few times, possibly different times to yourself.
I was not aware that the public right of way was in the field that runs directly along the embankment of the railway line, if this is the case then i publically apologise. At no point have i suggested that this person had thrown items to flush the owls, however deliberately or unintentionally the owls were being disturbed as a result of walking the embankment,again if this is a public right of way then i apologise. If there is a difference in the terminolgy "Flushed" or "Spooked" then again i apologise.
You have mentioned that you were following A lone photographer. As im sure your aware there are many lone photographers visit this site. You appear to jumped to an assumption that the guy i have mentioned and the guy you were watching are the same guy, may i add that i saw only one person, as mentioned.... 2 other people did not, as far as im aware follow the lone photographer. So perhaps you have not been watching the same lone photographer as i had been watching,with a good view, from the top of the hill next to the visitor centre.
Degsy, i would like to think that all birders who read, post or both on this forum are responsible decent birdwatchers, including yourself. I never actually thought for one minute this photographer would be a DBC or forum member. Im sure everyone has been guilty one time or another of going astray, probably because routes are not clearly marked or people are not familiar with a location. Im not on here to judge people, i mearly passed comment on what i had seen.
If anyone has assumed that they are the person who was mentioned, and i have caused offence then again i apologise.
Cheers
Ian
