Gregarious

House sparrows are always gregarious, but more so in winter when they flock together in large numbers.

In the morning and afternoon they disperse to feed, but twice a day — at midday and in the evening — they gather in dense shrubs or evergreens and chatter for an hour or more.  They sound a lot like this.(*)

You might not hear them in today’s cold weather but when you do it’s unmistakable.  They’re in a bush alive with birds … but you can’t see them.  I’ve tried to count them but they fall silent and hide when I approach.  I rarely see even one.

Here’s a flock in a tree, somewhat hidden but easier to see than inside a privet hedge!

House sparrows love each others’ company so much that, according to the Stokes Guide to Bird Behavior, some travel up to four miles to join the roost.

“Gregarious” works for house sparrows — from Latin gregarius (from grexgreg- ‘a flock’) + -ous (to make it an adjective).

(*)  The sounds at the link above are similar but not quite the same as winter chatter because they’re from a more intense breeding chase in April.  Listen to this segment from BirdNote for all the sounds house sparrows make.

    I experienced them doing this two years ago. My husband and I stayed at the hotel located on the bay at Lake Erie. We were coming into the hotel around dusk and there was all this chatter coming from two trees. I couldn’t see them but there was certainly a lot of birds right in the middle of all this human activity. I stopped and looked around and realized the two trees were protected from bone chilling wind coming off the lake. Now I know what was in the trees….txs!
