Bird watching

Hi there,
I went out the one afternoon to take some photographs of white birds that I had gotten a tip of was in the area. The person telling me about them did not know what kind of birds they were part from that they were quite large in size and flew away when he got close :-) No surprise there ha ha. Anyway I set off to take photographs of them. I put on a pair of shorts with lots of pockets on the sides for lens caps etc. and to that I had my 'new' company t-shirt those of you that have followed my blog knows that my compay t-shirts are bright pink in colour. I think that was my first mistake of this photo excursion. I very likely scared away any bird with any sense. I did fire off a few images towards an eagle that I saw or was it a large hawk? I am not sure. But it kept on flying away when ever I got close. I did chase it around for a while until he got tired of it and flew way off so that I had no chance of following it, so quite clever! I saw this early on my bird expedition so I was not at the lake where these white birds have been spotted so I set off trying to find them I had brought a book with me incase I had to wait for them. Once I got to the lake there was no birds in sight I scouted the area trying to find a good place for me to wait for them. But that is not as easy as it may sound since I had no idea of where they would be coming from and which part of the lake they would like to be at not that the lake is that large but still large enough to be at the wrong place at the right time..... well you know what I mean. Instead of sitting down to read I walked around trying to see other things to photograph while I was waiting. I did see the eagle again but only briefly he got a glimpse of me and few off and never came back I waited around for about 45 minutes. But no more eagles or the white birds. I am guessing that the white birds are a kind of heron because I have seen them in the area before and they can get quite large. But I did not get to see them this time. I did how ever photo graph some smaller birds. :-)
See images below, not the ones I had planned to photograph but they were there while I was waiting around and my bright pink shirt did not scare them off so easily or at all really. I guess for next time I should dress a bit more inconspicuous maybe some desert colored clothing would be a good idea so that I can blend in with the environment more.
Ps. if anyone knows the name of these birds below please let me know. Thanks!
Over and out till next time.
