Over the last couple of years I’ve noticed a group of crows that congregate along our street. They seem to show a great deal of interest in the large macadamia nut tree in the front yard. Today in the San Diego Union Tribune an article notes the boom in local crow numbers.
What has this got to do with wine? The article includes a photo by Don Kohlbauer of the Union Tribune which shows crows blanketing a vineyard northeast of Ensenada in Baja California, Mexico, every night at sunset last fall. Almost every post in the vineyard has a crow happily perched upon it. Happy until I guess someone from Crow Busters turns up! The interesting thing about crows and vineyard posts, according to the Crow Buster forum, is that they use the posts to congregate. Judging from the Union tribune photo and the photo on the Crow Busters forum this looks like a common, if potentially suicidal, activity for crows. Whether the crows constitute a serious threat to a vineyard is unclear. Although their diet does include fruit, it is quite varied. Still if you are a vigneron who wakes up every morning to crows occupying all the posts in your vineyard I think you might have cause for concern. If that is the case! Who you gonna call?
