Potpourri of North Dakota NWRs



Male Yellow Warbler
 Many small birds migrate between the prairies and tropics each year.  They arrive on the prairie in the spring, mate, lay eggs, and raise their young.  Shortening daylight hours in late summer spur them to migrate south to tropical areas.  These Yellow Warblers fly up to 3,000 miles during a single migration!



Veery






The Veery is the least spotted of all the American spotted thrushes and may be one of the easiest to identify.




Migration studies using radio telemetry show that they can fly up to 160 miles in a single night, and can fly at altitudes above 1.2 miles. Their wintering grounds are restricted to central and southern Brazil.






Tamarack Trees are scrubby-looking conifers.  This is the only conifer in Minnesota which turns gold and drops its needles in the fall.  Despite its dense, hard wood many Tamaracks fall prey to porcupines which have a fondness for the tree’s inner bark.











New trip birds for the day were Least Sandpipers
