Bird Finder is a feature of the PetersonGuides.com website that provides lists of birds for use in the Peterson Birds of North America and Peterson Feeder Birds of North America apps. The lists are free to download and are automatically imported into the app when you tap on a special web page link. You can also email lists to other Peterson Birds users.
To access Bird Finder lists, open the Safari web browser on your mobile device and go to PetersonGuides.com. Tap on the Bird Finder link to display a web page that guides you through downloading lists of birds for counties in the US and Canada. After selecting state and county, tapping on the icon of the app you are using (Feeder Birds or Birds) will import the list automatically to the app.
The objective with each Bird Finder list is to help you narrow down the number of candidate birds when trying to identify a bird you've observed. For example, if you are Marin County, California, and you observe a bird you are unfamiliar with, you will have to sift through many candidate birds before narrowing the list down and finally making a positive identification.
With the Bird Finder list for Marin County in your Peterson Birds app, you can quickly find birds that have been seen at that location and time of year. This dramatically reduces the number of candidate birds on your list, making it easier to positively identify the bird you observed.
Bird Finder lists are also useful when planning a trip to a known birding location. Download the appropriate list before hand and research which birds you are likely to see at that location and time of year. Then, when you are in the field, you can spend more time enjoying the birds and less time worrying about finding birds in your Peterson app.
Bird Finder has close to 40,000 lists for states and provinces in the US and Canada. The information used to construct each Bird Finder list was obtained from the Cornell Lab of Ornithology eBird database under license.
Bird Finder lists are equivalent to eBird.org bar charts. Each list includes frequency marks that simulate the eBird bar chart and show how frequently a particular species was sighted at that location.
There are 48 frequency marks per year, representing all sightings recorded by eBird for that location. Each month has four frequency marks, roughly correlating to weeks.
In a popular birding location, frequency marks can be considered indicators of abundance. The marks represent the number of times a birder submitted a list to eBird from that location, and how frequently a particular species was seen.
░ — indicates that there is insufficient information on this species at this location at this time of year. This means the species was observed at this location but no list has been submitted to eBird with the species at this time of year.
▢ — indicates that one or more lists have been submitted to eBird from this location at this time of year, but none have reported this species.
▁▂▃▄▅▆▇ — Indicates the frequency of sightings of this species at this location at this time of year. The taller the black column, the more frequently this bird was seen.
