Here is a map showing the bird density of HK, using data collected from the HK Winter Atlas.  Don't expect perfect data.  There are problem with accessibility, observer bias, and other bias as well.  However I think it is useful for members to see this data.

What does this data tell us?

Can't see the colour code.
What do the colours mean?

I think the size is too small

We are trying to finalise and confirm all of the data from the winter atlas surveys, with the aim of publishing results before the end of this year - this would include maps for all bird species recorded during the surveys. I apologise to all those intterested in the results and involved in the data collection for the length of time that it has taken between collecting the data and publication.

This map I think shows the number of individuals recorded during the survey in each square - darker colours indicate that more individuals were recorded (although I do not know what the cut-off point is for each of the colours)
