Bluetits

... There are other examples of the spontaneous spread of new habits in animals and birds which provide at least circumstantial evidence for the theory of morphic resonance. The best documented of these is the behavior of bluetits, a rather small bird with a blue head, that is common throughout Britain. Fresh milk is still delivered to the door each morning in Britain. Until about the 1950s, the caps on the milk bottles were made of cardboard. In 1921 in Southampton, a strange phenomenon was observed. When people came out in the morning to get their milk bottles, they found little shreds of cardboard all around the bottom of the bottle, and the cream from the top of the bottle had disappeared. Close observation revealed that this was being done by bluetits, who sat on top of the bottle, pulled off the cardboard with their beaks, and then drank the cream. Several tragic cases were found in which bluetits were discovered drowned head first in the milk!

This incident caused considerable interest; then the event turned up somewhere else in Britain, about 50 miles away, and then somewhere about 100 miles away. Whenever the bluetit phenomenon turned up, it started spreading locally, presumably by imitation. However, bluetits are very home-loving creatures, and they don't normally travel more than four or five miles. Therefore, the dissemination of the behavior over large distances could only be accounted for in terms of an independent discovery of the habit. The bluetit habit was mapped throughout Britain until 1947, by which time it had become more or less universal. The people who did the study came to the conclusion that it must have been "invented" independently at least 50 times. Moreover, the rate of spread of the habit accelerated as time went on. In other parts of Europe where milk bottles are delivered to doorsteps, such as Scandinavia and Holland, the habit also cropped up during the 1930s and spread in a similar manner. Here is an example of a pattern of behavior which was spread in a way which seemed to speed up with time, and which might provide an example of morphic resonance.

But there is still stronger evidence for morphic resonance. Because of the German occupation of Holland, milk delivery ceased during 1939-40. Milk deliveries did not resume until 1948. Since bluetits usually live only two to three years, there probably were no bluetits alive in 1948 who had been alive when milk was last delivered. Yet when milk deliveries resumed in 1948, the opening of milk bottles by bluetits sprang up rapidly in quite separate places in Holland and spread extremely rapidly until, within a year or two, it was once again universal. The behavior spread much more rapidly and cropped up independently much more frequently the second time round than the first time. This example demonstrates the evolutionary spread of a new habit which is probably not genetic but rather depends on a kind of collective memory due to morphic resonance.
