Figure Analysis of the Cowbird Paper


Cowbirds are parasitic birds that lay their eggs in other birds’ nests, relying on the other birds to raise their young, often to the detriment of the other birds’ chicks.


First, read Brood Parasitic Cowbird Nestlings Use Host Young to Procure Resources, by Rebecca M. Kilner, Joah R. Madden, and Mark E. Hauber. Science (volume 305, August 6, 2004):877-879.

For EACH of the FOUR figures, according to lecture and Pechenik’s reading for writing about results, answer the following questions:

  1. Does the figure stand alone, i.e. can you understand the main idea of the figure without reading the text?
  2. Was the type of figure chosen appropriate for the data represented, or would you have chosen a different type of figure. If so, what type would you have chosen and why?
  3. What is the Figure Title? Does the figure title express a complete idea?
  4. What data are presented on the x and y axes?
  5. Are the axes appropriately labeled and the units clear? The figures on the hand out are a little fuzzy. That is not what I mean by ‘clear’. What I mean is, are the units clearly understandable?
  6. Are the symbols clearly understandable and appropriate?
  7. Are the symbols well defined in either a legend key or a description?
  8. Optional. Any other comments?

When finished, you will have four marked figures.
