Annotated Checklist of the Birds of the Stroud Preserve, West Chester, Pennsylvania.

 

This is very much a work in progress and subject to a lot of change at any time. I will update it as needed. This list is largely based on my observations beginning in March of 2012 and the information provided on the preserve checklist. This list varies a greatly from the list posted on the preserve website, as I have observed 43 new species and revised the seasonal status for a number of birds. It should be noted that some of the waterbirds on the preserve list are unlikely to be seen in the future since the large artificial farm pond was drained and converted to a vegetated wetland.

Bold letters indicates that the species is new to the preserve list.

N – signifies that I have observed evidence that they are nesting such as carrying nesting material or constructing a nest or cavity, carrying food or fecal sacks or the presence of fledgelings or nest.

PN – signifies probable nesting, where I have observed adults carrying nesting materials, courtship displays, copulation or a singing male on territory on multiple days in appropriate habitat.  

n – noted as nesting on the preserve checklist but not by me.

 

The seasonal and abundance descriptions are intended to give you a general over all impression of their occurrence throughout the year at the preserve and is not intended to be a precise measure in anyway. Some species that are noted as "rare" or "uncommon" at the preserve, may be abundant a few miles away (i.e., Herring Gull or Killdeer). For rare and unusual birds I have given the dates and a few other notes when appropriate. For a more precise account of the birds of the Delaware Valley consult the DVOC Checklist.

Abundant – lots of birds in the right habitat in the right season.

Common– not quite as many as above, but likely to be seen in in the right habitat in the right season

Uncommon– present, may not be seen in the right habitat in the right season.

Occasional– Only seen once or twice in a season.

Rare– Only one or two records. Not expected at the preserve or rare on a regional bases.
