Are there additional animal studies about superstitions? In one particular case, Skinner decided to go random on his hungry
pigeons. He dropped food into the box at completely random times,
independent of any behavior on the part of the pigeons. But the
behavior of the pigeons, he found, didn't stay random. After a few
drops of the food, the pigeons began exhibiting certain consistent
behavior. One circled counter-clockwise, another spun around in
circles; seventy-five percent of them exhibited some kind of odd
behavior.   Skinner concluded that the pigeons had come to display
'superstitious behavior'. It was like the superstition of gamblers who
believe they have a lucky hat. If the gambler wears the hat, they
can't lose. If the pigeons circle the cage counter-clockwise, they
will bring on food pellets.

Seems curious that this wouldn’t have been pursued as an avenue of study with other animals.
Can anyone find me a citation of such studies and does anyone know if the study has been repeated elsewhere?
For instance, the same behavior was also shown in orang-utan and dog. Already two years after the study by Skinner (1947) mentioned in the news article, Kellogg (1949) gave a review of some of the experimental results, but advocates a less anthropomorphic interpretation:

  Abstract
  
  The orang-utan and dog as well as the pigeon have shown "superstitious" behavior. It has appeared in conditioning and multiple-choice experiments. Interpreting such behavior as superstitious is mentalistic and anthropomorphic. "An alternate and less complicated interpretation would be that these activities—whether relevant or irrelevant to the solution of the problem—are ordinary instances of the association of a sequence of movements with a reinforcing stimulus."


Interestingly, superstitious behavior is still a topic of interest for research done with humans. See for example the results of a PubMed search with this search term: http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed&amp;cmd=DetailsSearch&amp;term=%22superstitious+behavior%22&amp;save_search=true
