Ecology & GIS Sites

There are lots of great ecology sites that I've only become recently aware of.  These include:
1) eBird: http://ebird.org/content/ebird/
This is a citizen science site for bird tracking.
2) The IUCN Redlist: http://www.iucnredlist.org/
3) Map of Life: https://mol.org/
4) Census of Marine Life: http://www.coml.org/ (specifically OBIS, Ocean Biogeographic Information System - http://www.iobis.org/)
Good tutorials for extracting and mapping the spatial data from these sites would be a good next step.
