Felger describes the sorts of data an ornithologist would be interested in collecting and then delineates how to create a spreadsheet (though he doesn't use this term) for collecting this data.
In a follow up article five years later, he suggests using a card index system instead. See: @Felger1907 whith notes at: https://hypothes.is/a/qeki7oU4EfGv8QNy5SVDgA

Felger, A. H. 1907. “A Card System of Note-Keeping.” The Auk 24(2): 200–205. doi:10.2307/4070853.
Ornithologist A. H. Felger describes the use and form of a custom card index system for creating a paper database of data for tracking and counting birds.
In particular he recommends it over prior uses of journaling methods. He suggests the ability to look at multiple cards in a row to be able to more easily extract usable data versus those older journaling methods.

In running overa hundred cards on a certain species that one is studying it is avery simple matter by reference to the 'barred cards' to selectthose that contain notes on 'mating,' 'nest-building,' or the like.(3) If the cards on any given species are arranged chronologic-ally in a horizontal row, one will have in line before him forvery easy study all the notes with reference to any desired phaseof the bird's life history
Felger broad describes how to use index cards to create a paper database for ornithology.
