Savannah Sparrows in Griggstown


With last night's heavy rain storm, and generally unfavorable winds for migration the last few days, it was hard to predict how good the birding would be this morning. We headed down to the Griggstown Grasslands to see what would be in the meadows there. As it happens, two groups of birds stood out for their abundance.

The first group were the sparrows, and principally savannah sparrows. There must have been about fifty of these tiny spritely birds clustered into a few fields right around the parking lot. At times there seemed to be one on every dried mullein stalk. These were not the only sparrows. They were accompanied in the meadow by several richly-colored swamp sparrows and many song sparrows. A few field sparrows and a single chipping sparrow rounded out the mix. Other areas of the preserve held more song and white-throated sparrows. Several palm warblers were scattered around the grasslands.

The second large group were the diurnal raptors. These were notable both for diversity and for numbers of individuals. First-year harriers were new arrivals at the grasslands this month. A Cooper's and several sharp-shinned hawks made brief appearances. At one point a group of four red-tailed hawks circled overhead; there may have been more than that, as red-tails were visible at several points on the walk. Kestrel flybys included one male that circled and gave great looks. Several large kettles of vultures - including one of about twenty black vultures - passed through.

Fall foliage season is well underway, though it has not reached its peak yet. The trees along the canal were especially beautiful where they reflected on the water in the morning light.

Update (10/21): After seeing a lot of white-crowned sparrows at Sandy Hook, I think that two of the sparrows we saw yesterday were actually immature white-crowned sparrows.
