Notes on sexual differences within certain species of birds.
Encloses some queries.
Would also like information about proportion of male to female humming-birds.
Reference to OS’s paper in Ibis, vol. 2.
Shot a sandpiper in Norway, the hind toe of which was clasped by a freshwater bivalve.
Sends replies to CD’s queries about sex ratios in humming-birds.
CD thanks OS for answering his questions and especially for giving the case of the sandpiper; "such little facts are my delight". [See 6253.]
