This is a bit of a rant having had 4 recent experiences with what I deem inconsiderate bird photographers.
In social media it is common to read that opportunity should be given to all no matter their country of origin etc.
When it comes to bird photography I take the position that first to location, all others should stay clear. Exceptions where birds are accustomed to multiple humans such as some refuges, are certainly acceptable.
Recently when photographing ducks I had several occasions where perhaps thoughtless newcomers show up making lots of noise with very expensive teles and pro cameras, standing up, walking around in camo gear thinking that they are hidden fron sight.
I will say this. I refuse to move anywhere near another photographers space and usually move on so as not to interfere with their experience and by my motion disturb the birds.
I find those that dont heed this courtesy will find they have perhaps destroyed opportunity for those first on site, and for themselves.
Lucklly and due to stealth and careful stalking I did capture some fine closeups of wild birds prior to disturbance by others. In fact I had 3 birds within 10 feet at ine point.
What amazes me is the lack of respect and consciousness of others.
One fellow had the audacity to move within 25feet from me, standing up, making noise, and chatting with me while I was hunkered down low, hidden behind foliage and quiet, waiting for birds to come to me.
Needless to say, the birds scattered and my good experience ended.
A word of advise. Stay clear of your fellow photographers when they were first on site. Judge carefully before you move into gheir space.
