<div dir="ltr"><div>I think it's too early to assume cause and effect. I've lived in this house now for twenty years and I have Anna's at my feeders all year and Rufous every summer between late March/early April and late July/early August. What I see when the two species interact is that the Rufous, although smaller, are more aggressive. I consistently see them chasing Anna's away from the feeders. That's not an obvious parallel for the barred owl and spotted owl situation or grey squirrel and red squirrel situation in the UK. <br></div><div><br></div><div>Louise Rutter</div><div>Kirkland<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Nov 11, 2024 at 6:53 AM Tom Benedict via Tweeters <<a href="mailto:tweeters@u.washington.edu">tweeters@u.washington.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>

> 3. As for native birds, sadly, enter Rufous Hummingbird. You will not like what you see. But it is completely consistent with what I have seen at my rural place 20 mi SE of Portland. 50 years ago,Rufous (only) were a common breeder and present at my feeders seasonally as is well known. Then Anna's finally made it here say 40 years ago and both were common for the mid 20-30 years. But in the last 5 years Rufous have been virtually absent here.<br>

Same experience here. Given the obvious cause and effect, are there any plans to hire sharpshooters to cull the Anna’s population so that Rufous can regain their numbers?<br>
