The Birdfeeder Experiment: Week 2 Report
When I first installed my feeders I envisioned a setting not unlike Cheers with an “everyone knows your name” vibe and a set of regulars who were chummy with one another. In reality, I’ve opened the Mos Eisely Cantina on the wrong side of Tatooine (hint: it’s a Star Wars reference). My feeders have been taken over by a rough-and-tumble gang who communicate by brawling among themselves and intimidating any other species that dares stop by. I’m speaking, of course, of House Sparrows.
Those adorable little rotund-in-the-middle flyers had me fooled at first. They arrived cautiously, seemed uncertain about the new venue, and then hesitatingly sat down and ordered their first seeds. I eagerly welcomed them. But the more they visited, the more I wanted to know about who they were. And that’s when I learned their dark secret: the House Sparrow is a non-native species with a tendency towards taking over the nests of native birds.
House Sparrows were introduced in Brooklyn, New York in 1853 (there was another group introduced two years earlier, but they did not survive). I had read initially that they were brought over by homesick Europeans who craved some familiarity in their new colony but have since dug deeper and found a classic story of pest-control gone awry. There are many write-ups recounting the arrival of House Sparrows in North America but one of the more readable (online) versions I’ve come across recently can be found here on the Hatching Cat blog.
House Sparrows have been called one of the most common animals in the world; since the nineteenth century, their population has been expanding exponentially. But they haven’t simply adapted well to the new environments they’ve been introduced to – they kicked the locals out. That’s right, our little House Sparrow has a nasty tendency of stealing the homes of Bluebirds, Tree swallows, Purple martins, Chickadees, and other native species. And by “stealing the homes of” I mean suffocating the eggs or kicking out the chicks of native species to settle their own nests.
So what is a new feeder host to do? I can’t quite turn a blind eye now that I know the habits of my most frequent customers, but I also don’t want to give up on the feeder experiment (my breakfast really does seem to taste better with my nose against my window, watching the feeder activity).
The (Ongoing) Search for Solutions
The online advice talks about putting out seeds that House Sparrows don’t like (there are some more drastic suggestions as well that I was not willing to consider – there are some people out there who really don’t like House Sparrows). Sunflowers are technically on the no-like list but I think that by providing the de-shelled version in hopes of making less mess at my feeder, I proved that they actually love sunflower seeds (my little troupe sucks down an entire feeder of seed per week).
Suet and mealworms (the other selections I currently have out) are also on the list of dislikes for House Sparrows. For the two weeks they’ve been out, they’ve seen very little action – I even tried soaking the mealworms in an attempt to make them plumper and more appetizing (there is nothing stranger to see in the morning than watching a woman who is an egg away from being vegan pouring hot water over a bowl of dried insects while she makes her morning coffee).
I was quite discouraged and had been planning to head to the store to try all new seeds – and then I had a mystery visitor. When I got home Friday night, the mealworms were missing – and not just a few, I mean ALL of them. I decided to delay my Week 2 Report and investigate over the weekend.
Saturday I filled the bowl, waiting as long as I could before heading out for the day and saw nothing. When I returned home that night: the mealworms were gone. Sunday, I repeated the process, again seeing nothing until the evidence of an empty bowl greeted me upon my return home in the evening. The suet was noticeable lower as well.
So somebody IS visiting despite the territory the House Sparrows have attempted to claim. I suspect it’s my resident Blue Jay – I’ve seen him hesitate by the feeder but he’s very skittish so he may be waiting until I leave for the day.
Week 2 Lessons and Next Steps
The weekend has renewed my hope at attracting multiple species to my feeder – even if it’s only a gang of House Sparrows and a single Blue Jay at the moment. I do think I will hit up the store this week to investigate other options in seeds. For starters, if it is only the House Sparrows eating the seeds in the tube feeder, I don’t think they need the expensive sunflower hearts.
I don’t think any seed choice will fully discourage the House Sparrows (and I honestly do think they’re adorable to watch despite their more problematic relationships with other birds) but I don’t want to cater exclusively to their bellies either. I’ve been watching eBird spottings in my area to get a sense of who is in the neighbourhood and researching their favourite treats. I currently have an orange hanging out on the top of my feeder pole to see if that might draw anyone new in…
