Bird Identification

This is a basic interface to the audio and image files at The Cornell Lab of Ornithology.

Code

The file "base.py" is basic script for starting things up in a python terminal. Python3 is recommended.

The functions for testing your knowledge are as follows:

audio_quiz(birds, key='name')
image_quiz(birds, key='name', figsize=(7,7))
video_quiz(birds, key='name')
taxonomy_quiz(birds, key='order')

Each function requires a pandas dataframe as an input (birds), with an optional parameter called key. For the audio, image, and video quizzes, this key can be from ['name', 'order', 'family', 'species'], while for the taxonomy quiz if must be from ['order', 'family', 'species']. The figsize parameter allows you to change the image size.

The video links have a limited duration of about ~1 hour. If the links stop working, simply exit the quiz (type "q" and hit return) and call the function again.

Functions that can be used to create dataframes are the following:

get_birds_by_family(*families)
get_birds_by_group(*groups)
get_birds_by_order(*orders)
get_birds_by_name(*names)

Each function can take a series of strings referring to birds of the designated type. Thus a few usages are the following

waterfowl = get_birds_by_group('geese', 'swans', 'ducks')
waterfowl = get_birds_by_order('anseriformes')
waterfowl = get_birds_by_family('anatidae')

If you want to quiz yourself by looking at various images of waterfowl, and increase the figure size, this can be done as follows in a python terminal:

from base import *
waterfowl = get_birds_by_family('anatidae')
image_quiz(waterfowl, figsize=(9,9))

If you are using an ipython terminal, then run base can be used in place of from base import *

To run an audio_quiz on the birds defined in the dataframe custom_list, and require that the answer refer to the order of the species, we can do the following

audio_quiz(custom_list, key='order')

Similarly, to run a video_quiz on the birds that we've seen and test on the family of the bird we can call

video_quiz(class_birds, key='family')

To exit a quiz, simply type "q" and press return. The audio can be repeated by entering "r" and pressing return; the same works with the video quiz.

If wanting to go the Cornell website for a particular bird, simply pass the name of the bird as a string into the function open_browser. If there is an apostrophe in the name, precede with a backspace.

open_brower('bald eagle')
open_browser('ross\'s goose')
