-- * Region hotspots
-------------------------------------------------------------------------------

-- | Get all hotspots in a list of one or more regions ('RegionCode').
--
-- For example, get the hotspots in Albany County, Wyoming and Park County,
-- Wyoming that have been visited in the last 5 days (using @-XOverloadedLabels@
-- and @-XOverloadedStrings@):
--
-- @
-- askEBird $ regionHotspots "US-WY-001,US-WY-029" (def & #back ?~ 5)

-- See the [eBird API documentation for the corresponding
-- endpoint](https://documenter.getpostman.com/view/664302/S1ENwy59#f4f59f90-854e-4ba6-8207-323a8cf0bfe0).

-- | Optional parameters accepted by the 'RegionHotspotsAPI'.
--
-- Note that 'defaultRegionHotspotsParams' (or the 'Default' instance's 'def'
-- value) may be used to accept the defaults of the eBird API.
--
-- Additionally, note that there are optics available for manipulating this
-- type. For example, if you would like to just set the
-- '_regionHotspotsParamsBack' field to 10:

-- * Hotspot info
