Mortality on wintering grounds: Unreasonably cold temperatures on the wintering grounds kills thousands of birds, resulting in 30-90% population declines of migratory birds. For example, between 27000 and 62000 ducks, mostly tufted duck and common pochard , starved to death during a very cold winter in March 1986.
The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources are artesian wells. This is possible even if the outlet is in the form of a 300-foot-deep (91 m) cave.

In March 1904, 1.5 million migrating birds died in Minnesota and Iowa during a strong snowstorm. [5] According to The Guardian, this was the largest avian mortality event on record in the region. [5] Records of MMEs have been kept since the 1880s. [5] MMEs of this size are rare, however, and few before or since have been as big as the 1904 event.
