Below is a self updating gadget from eBird/BirdTrax. It shows New Brunswick bird sightings reported to eBird in the last 14 days. The default view is the Sightings Tab. Google map locations can easily be displayed.
Google Map Locations
In the Sightings and Rarities Tabs, click on the plus sign (+) to the far right in the gadget. A box pops up with some links and one of them will open the Google Map location of the sighting in a new window.
Also, in the Rarities Tab you can just click the word (map) found in brackets.
Why doesn't this work with Internet Explorer?
The gadget maker has an explanation here.
