Observations on the Common Frog (Rana temporaria).

Over the past few years I have been observing the common frogs in my garden pond. Since 1985 I have noted that they all come out of hibernation together, on April 1st each year. This is in variance to the paper written by I.M.A. Sleeper in 1988. Female and immature frogs usually hibernate under logs, stones and other such places. The males favour lying in the mud at the bottom of the pond, lazing around breathing through their skin by the simple process of oxygen diffusing from the surrounding water into the blood vessels in their skin and carbon dioxide diffusing from the blood vessels in the skin into the water.


Another noticeable observation is that all the frogs appearing before noon are male

Why frogs of only one sex appear is of paramount importance to my future research. My findings agree with the paper by A. Cekshuall who also noted this highly interesting phenomenon. I would also like to point out that this paper is very similar to the one I delivered to the Fred Frog Society last year.


This lecture was presented at Toad Hall, Newtvale last year. The three members of the audience were so enthralled by my talk they have engaged me to do the same lecture next year.
This, however, is a digression from the serious business of my paper. I would certainly like to hear from other people who would either agree or disagree with my findings.
