Actually an increase over the past few years. Trees, Barns, Cliffs and some VGs. We have a pasture so they have good feeding opportunities. I have been battling the House Sparrows for a couple years now. We have five nest boxes spread out and the male House Sparrows try to defend and possess all of these boxes. Once they finally pick a box, and stop harassing all the other birds that are trying to occupy a box, I wait and then keep removing their nests. The sparrow are pretty industrious. If I remove their nest in the morning they just rebuild it by the end of the day. I now take the nest material a good distance from the box. One House Wren took over a sparrow box and threw all the eggs out! Impressive! </div><div dir="ltr">One thing that got me started on this was a couple years ago I found in a box a dead adult VG that a sparrow had killed. </div><div dir="ltr"><br></div><div dir="ltr">As we have farm animals close next door on the neighbors property, with lots of feed on the ground, the House Sparrows get established and multiply quickly, as do the rodents. I can see waves of sparrows of up to about 15 flying around. Trapping and dispatching the House Sparrows is now unfortunately becoming a viable option. </div><div dir="ltr"><br></div><div dir="ltr">At Deer Lagoon Preserve we feel the numbers have increased as there are tons of insects for them to eat. In the evening the swallow numbers are truly impressive. </div><div dir="ltr"><br></div><div dir="ltr">Carlos</div><div dir="ltr"><br>On Jul 22, 2024, at 08:34, Dennis Paulson via Tweeters <tweeters@u.washington.edu> wrote:<br><br></div><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=utf-8">Steve, thanks for another perspective, and I know House Sparrows have been shown to be involved in displacing swallows. But interestingly, House Sparrows have also declined dramatically in Seattle, I think not just in our wooded neighborhood. When we first moved here, we had them in the yard all the time, thronging our feeders day after day. In the summer of 1996, up to 30 birds visited the feeders at once. By 2010, they were in the yard only occasionally, and the last ones we saw were a family that visited the yard briefly in June 2021. And we’re watching those feeders every day when we’re in town.<div class=""><br class=""></div><div class="">In this species, I presume a loss of nest sites may have caused the decline, so that could be a cause of at least some of the swallow decline as well.

This should eliminate House Sparrows, but be suitable for smaller native species. Here's an example of a hole reducer: </div><div class="gmail_default" style="font-size:large;color:#073763"><a href="https://nature-niche.com/collections/bird-house-accessories/products/1-125-diameter-portal-for-chickadee-houses-genuine-copper" class="">https://nature-niche.com/collections/bird-house-accessories/products/1-125-diameter-portal-for-chickadee-houses-genuine-copper</a><br class=""></div><div class="gmail_default" style="font-size:large;color:#073763"><br class=""></div><div class="gmail_default" style="font-size:large;color:#073763">good birding, </div><div class="gmail_default" style="font-size:large;color:#073763"><br class=""></div></div><br class=""><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 22, 2024 at 7:29 AM Dennis Paulson via Tweeters <<a href="mailto:tweeters@u.washington.edu" class="">tweeters@u.washington.edu</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;" class="">Hans, I think swallows have disappeared from much of the Seattle urban/suburban area. Barn and Violet-green were all over the city 40-50 years ago. When we moved into our present house in Maple Leaf in 1991, we had Barn, Violet-green and sometimes Tree over the house on a regular basis, also Vaux’s Swifts. Within a decade or so all had disappeared, and our sky was empty of these birds, never to be seen again. As I drove around town, I noticed the same thing. Both Barn and Violet-green had been in most neighborhoods, but not anymore. These two species nested on buildings, on ledges or in holes, and I wondered if there was a movement to tidy up houses that was eliminating their potential nest sites.<div class=""><br class=""></div><div class="">But I suspect it has much more to do with the decline of small flying insects over that time, not a thing that is obvious to us, earthbound as we are. We still have a few subsidized colonies of Purple Martins, but they are feeding largely on wasps and bees, which are still around, and dragonflies, which they can find by flying some distance from their nests.<div class=""><br class=""></div><div class="">Dennis Paulson</div><div class="">Seattle<br class=""><div class=""><div class=""><br class=""><blockquote type="cite" class=""><div class="">On Jul 22, 2024, at 12:20 AM, Hans-Joachim Feddern via Tweeters <<a href="mailto:tweeters@u.washington.edu" target="_blank" class="">tweeters@u.washington.edu</a>> wrote:</div><br class=""><div class=""><div dir="ltr" class="">Has anyone else noticed that there seem to be less swallows around?
