title: Multi-Layer .gdb files in Python?
body: <p>I'm trying to read in some .gdb files(folders?) from <a href="https://www.sciencebase.gov/catalog/item/55897deae4b0b6d21dd61c9d" rel="noreferrer">here</a>: .</p>
  
  <p>I use GeoPandas and do the following:</p>
  
  <pre><code># file from local path
  mallard = gpd.read_file('./bird-species/E00039600_mallard.gdb/')
  # geopandas included map, filtered to just this hemisphere
  world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))
  westhem = world[(world['continent'] == 'North America') | 
                  (world['continent'] == 'South America')]
  
  # making sure the coordinates line up:
  mallard = mallard.to_crs(world.crs)
  
  #establishing figure axes
  base = westhem.plot(color='white', edgecolor='black',figsize=(11,11))
  
  # cmap because I'd LIKE the multiple layers to exist
  bbw_duck.plot(ax=base, cmap = 'Reds');
  </code></pre>
  
  <p>The output looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/XKTWI.png" rel="noreferrer">lousy map - one color</a></p>
  
  <p>Is there a way in GeoPandas, or Python (Jupyter Notebook) in general to see all the layers?</p>
