  1. Hello Nasy, I found you when I was looking at my profile and saw other profiles in Athens. I live in Kifissia. I'm so sorry to hear about what happened to you. Maybe since we live in the same city (although not so close) we can support each other with info and resources as well. What do you think? Cheers, Renate
  2. vascript:emotic('{Feel-good-0002006E} ') Hey, I got a lead!!!!!! One of the few parrot yahoo groups I'm a member of told me about another Yahoo group called LegBandNumbers. The wonderful lady who manages the list helps people trace their birds. She got me my breeders name and email address. I will write to them today. Wish me luck!! javascript:emotic('{Feel-good-000200BB} ') Renate {Feel-good-000200BB}

  4. That's easy! G - All of the above, of course. I didn't know about the last fact, though. I'll see if I can think up a little known fact to present - this is fun! Renate
  5. D all of the above and E none of the above.... Who says that AGs are gray? We humans don't really know what color they are since they see each other quite differently... See the quote from this url for instance: http://www.bio.bris.ac.uk/research/behavior/icc_vis.htm "Colour Vision in Birds Bird colour vision differs from that of humans in two main ways. First, birds can see ultraviolet light. It appears that UV vision is a general property of diurnal birds, having been found in over 35 species using a combination of microspectrophotometry, electrophysiology, and behavioural methods. So, are birds like bees? Bees, like humans, have three receptor types, although unlike humans they are sensitive to ultraviolet light, with loss of sensitivity at the red end of the spectrum. This spectral range is achieved by having a cone type that is sensitive to UV wavelengths, and two that are sensitive to "human visible" wavelengths. Remember, because 'colour' is the result of differences in output of receptor types, this means that bees do not simply see additional 'UV colours', they will perceive even human-visible spectra in different hues to those which humans experience. Fortunately, as any nature film crew knows, we can gain an insight to the bee colour world by converting the blue, red and green channels of a video camera into UV, blue and green channels. Bees are trichromatic, like humans, so the three dimensions of bee colour can be mapped onto the three dimensions of human colour. With birds, and indeed many other non-mammalian vertebrates, life is not so simple. As well as seeing very well in the ultraviolet, all bird species that have been studied have at least four types of cone. They have four, not three, dimensional colour vision. Recent studies have confirmed tetra-chromacy in some fish and turtles, so perhaps we should not be surprised about this. It is mammals, including humans, that have poor colour vision! Whilst UV reception increases the range of wavelengths over which birds can see, increased dimensionality produces a qualitative change in the nature of colour perception that probably cannot be translated into human experience. Bird colours are not simply refinements of the hues that humans, or bees, see, these are hues unknown to any trichromat." So we really don't have a clue, do we? Cheers, Renate
  6. Hello All, Does anyone know how to read the codes on the bands of the birds? I know that my CAG Alex was born in 2008 but I would like to trace the breeder in order to find out the bird's age. Can anyone tell me how to read the codes on its ring, and if you know a website or database I can search, that would really be great. I was told that that the bird is from a breeder in Belgium. These are the codes on the ring: 16 NB08 FQ22 The ring is blue coated aluminum. Thanks very much for your help! Renate Athens, Greece
