How do I use this site?
This website allows you to see populations of 13 different birds for various bays & counties in Texas. To view the populations first click on a bay (Bay Color) or county (County Color) on the map. As you move your mouse over each location you will see its name displayed.

You can navigate around the map by clicking and dragging with your mouse. You can also zoom in using your mouse wheel or using the zoom control on the top left side of the map.

Once you click on a location on the map a small popup will be displayed with icons for each of the available species of birds. Click on their icon to display a graph of their population over time. You can view a graph of multiple birds at the same time by pressing shift and then clicking on a bird's icon.

Using the Map
This website uses Google Maps to display the bays & counties that you can view bird populations for. If you've used Google Maps before, you can use this page just like you use Google Maps. If you haven't used Google Maps before, here are some tips:

Moving Around the Map
Navigation Buttons You can move around the map by clicking your mouse anywhere on the map and dragging. You can also use the navigation buttons (shown on the right) to move around.
Zooming
You can also zoom in and out on the map by using your mouse wheel. You can also use the zoom control located underneath the navigation buttons.
Note: If you zoom out too far the map icons will disappear. They will be displayed again if you zoom in closer.
Change the Map Type
You can also change the map type from a map to a satellite view to a hybrid between the two by clicking their corresponding icons in the top right corner of the map.
