2023 Species-by-Species Birding Almanac for Philadelphia County, PA
The purpose of this document is to provide an idea of the periods of the year during which bird species in Philadelphia County, PA are observed based on historical records. The document presents the following information on a species-by-species basis:
- The first and last days of the period(s) during which each species can be observed. The font size of the dates indicates the relative frequency of observation: larger fonts indicate a period when the species is more likely to be observed, smaller fonts a period when the species is less likely to be observed. Note that because these relative frequencies are calculated on a species-by-species basis, the same size font for two different species does not necessarily indicate that those two species are equally easy to observe.
- The observation code (abbreviated “Obs. Code” below) for each species. This code loosely corresponds to the observation likeliness of the species (over the whole the year), ranging from almost certain (1) to very unlikely (4). See the Bird Observation Codes document for additional information.
This document was established using eBird histogram data for Philadelphia County, PA from 2018 to 2022. Each entry contains links to the species’ eBird webpage, the species’ eBird full bar chart for the area, and the species’ eBird map of where it has been observed in the area.
Limitations
The present guide provides only an indication of bird observations across the area. The accuracy of these indications may suffer from several limitations, some of which are listed below:
- The guide only covers the species that appear in the eBird database for the area between 2018 and 2022, including naturalized, provisional, and escapee exotic species. Furthermore, it does not currently include rare birds.
- The document does not intend to replicate the level of detail that eBird’s bar charts provide. Because of the simple format used here, the document only provides the main patterns of observation of bird species. As a result, species may also be observed outside of the dates indicated here. For more accurate information, the detailed eBird bar chart can be accessed using the link provided with each entry.
- The document may seem to suggest that some known year-round residents are not observed during certain periods of the year. This is due to a lack of sufficient year-round observations, and as a result, the data does not show the year-round presence of these species.
