This is the first time salt secretions have been obtained from any member of the Order Gaviformes. Gaviformes & Podicipediformes are the only two orders of birds when spend time in salt waters that had not been tested for presence of a functional salt gland.

Secretion occurred in very small amounts starting 1/2 hour after injection & lasting for another 1/2 hour. No external drops formed & much of the liquid probably evaporated at times when my tube was not in the nostrils. The Loon was released in Clerenges Lake immediately after the experiment & he swam away a short distance & then proceeded to dive for short distances as he receded into the fog.
