If you do the math on the ability of this species to reproduce (2-3 nestings with 4-7 chicks per nesting) and the average life span (roughly 12 years), you realize how eliminating one breeding pair has the potential to have a tremendous benefit on species diversity, even within a small area. Kate: Sounds like you have had a lot of success. The Huber trap is a great idea. There are also others that are nice. Here is the web site for one: http://www.vanerttraps.com/universal.htm You may be aware of this, but I just think this caution bears saying for those who are reading: The one problem with putting in-box traps in a bank of martin houses is that you are likely to trap native birds as well. You have to monitor these kinds of traps hourly (which might be hard given the height of them) to make sure that the trapped bird is the intended target species. If it is not, you actually risk the life of the native bird(s), which, of course, is illegal as well as inhumane. So monitoring is absolutely essential. I would agree with everything else that you have mentioned. Certainly the males are the ones that control the area and have the most potential to harm native birds through passive and active competition. Most people who do this would agree that one of the best ways to catch them is with in-box traps during the heat of the nesting season. They are very saavy about ground traps. You can sometimes bait the ground traps with nesting materials that are glued to a heavy piece of wood (ripped plastic tarp material, trash, tissues, yarn, etc.). The best season to catch the adult males (and females) is the early spring. During the summer, it is best to use a ground trap baited with white bread. You can catch young birds and females by the dozen this way. I have included a link for a very good repeating ground trap. Good luck to you Rose. I think that everything here is really true and if more people would consider doing a small piece of this big problem species diversity could be noticably improved. Of course, this is all contingent on the laws in Canada. Here is a link that might be useful: Repeating Ground Trap

You removed a Chickadee nest?? Why on earth would you remove a Chickadee nest?? They are very low on the totem pole as far as successful nestings since they cannot fight off larger cavity nesters, plus they usually only have one brood per season so they need all the help they can get. I LOVE Dees! I have had them nesting here for the last three years and I would never never remove one of their nests!! I protect them as much as I could and if a Blue pair wanted the box that a Dee already had then I would put a hole reducer on the box so the Blues couldn't have it! I have tons of TRES that take all the boxes around here but I haven't removed any of their nests either, just keep hoping the Blues find an empty box and nest. The Blues around here are always the last to start nesting so they get what is left pretty much of the nestboxes. I have one pair of Blues, one pair of Dees and six pairs of TRES all nesting right now. Blues love mealworms but as far as getting them to stay in your yard and nest, there is no guarantee. The male finds the nesting sites but the female needs to approve of it. She makes the final pic. If she likes the nestbox she will stay...if they found something better elsewhere they will go there. Alot depends on the availability of nestboxes around your area. If they have lots to choose from they could go anywhere but if there aren't alot of spots for them to choose from then maybe they will choose your yard. However if you aren't prepared to let other native cavity nesters use the nestboxes you put up then you shouldn't be offering nestboxes. Oh and hopefully all your nestboxes are mounted on slick metal poles (conduit works best) with predator baffles and at least 15 feet away from trees or fences. Donna

I just stumbled upon this post as I try to prevent the recurring problems from Barn Swallows again this year. Unfortunately, the image is no longer available and I cannot see how you hung the netting. We have a colony of Barn Swallows that roost at our apartment building each year. The landlord hates them, but a former tenant had posted signs everywhere about how it was illegal to remove the nests. It was only through my own research that I realized it was only illegal while eggs or babies were in the nests, and those tenants moved out this winter. In addition to nesting on top of our buildings lights, covered walkways, and eaves, my apartment and the one next door have outdoor entrances from our gorgeous courtyard and patio which have covered stairwells. Each year, the swallows fly through these two stairwells like its the Lincoln Tunnel, dive bombing anyone who tries to walk on the stairs. They build their nests on the outlet boxes or porch lights. The first summer we lived here, I thought it was really neat to have such a close view of their lives, as I would often sit on my steps and could watch the babies as they grew, taking great care to be quiet and non-threatening. However, I also found that my porch steps and exterior wall were covered with bird droppings. They are also very very noisy when there is an entire colony of them outside of your windows. All of the "teenage" birds hang out in one of our courtyard trees outside of my window, which my cat loves but can actually drown out any conversation or television in our living room. Then I experienced what I thought were bed bugs in our house. I had tiny bites head to toe and could constantly feel them crawling on me despite rarely being able to see anything. It got so bad that I was getting the bites infected from itching all the time, and I couldn't sleep because I could feel the bugs crawling on my skin as soon as I tried to relax. I finally captured a few and took them to the University's Department of Entymology, who identified them as bird mites. That experience was HORRIFIC. I was ready to burn our entire building down after reading that the bird mites multiply much more quickly than bed bugs and are nearly impossible to remove. Luckily, the mites died off when the birds finally left for the season, but I can no longer sit outside on my wooden stairs because I fear contracting them again. The next spring, I tried the knock-down method, just on my own stairwell. I would open my screen door 2 inches and use a broom handle to knock down the nests up to 7 times a day. The swallows became very agitated, and and two attacked my daughter's head when she got home from school one of the days. I couldn't sit inside and repeat this process forever, though, and they got their nest up one day while I was off at a 12 hour work shift. The outlet covers they use are too high up to see into, and I knew that some other nests already had eggs, so I couldn't knock it down, more out of compassion than fear of charges. This will be our third summer here. Our elderly landlord has given up trying to prevent them from nesting even in the building entryways. I have removed my porch light cover so there is no solid surface to nest on, but the outlet box cover is too high up and I can't put a ladder on the stairs to reach it. I have considered trying to throw a cotton ball soaked with peppermint oil up there (it has worked in the past for mice and spider problems), or hanging a bunch of cut aluminum as a mobile at the top of the steps (I have heard that the reflections off the metal scare birds off), but I simply can't go through another year of this if those methods don't work. I saw that I could use something to create a 45% slope where the nest to prevent them, but again... getting up there is an issue. I am curious to see how you used the mesh. Could you please share the picture again?

I think you did the best thing, Chris, but I must comment regarding your mentioning that bluebirds are portrayed as timid and lacking in skills to defend their territory. In the past, bluebird territory differed from that of house wrens. As someone who has been a bluebird enthusiast and monitor for many years, I must say that wrens are no longer reading the manual and are not following the rules on where they are supposed to nest! Bluebirds can and do defend themselves and their nests (Dave, you need to repost your bluebird/hosp battle photos), but house wrens are the sneakiest of birds. They are quick and can be in and out of a nestbox in a matter of seconds. BlueBars can tell you of the battle between a bluebird and a house wren inside a nestbox and I'll simply say that the wren left minus some feathers. Unfortunately, even an incubating female bluebird must leave the nestbox occasionally and that is when the wren seems to appear. House sparrows are another thing entirely. They are non-native and are extremely aggressive towards not only bluebirds but towards all other native cavity nesters. A bluebird, tree swallow, chickadee or titmouse is simply not equipped to battle a house sparrow inside a nestbox. I have witnessed the result of such attacks too many times and hope it is something you never experience. Since man, in his great wisdom, brought house sparrows to America to "help", house sparrows have wreaked havoc not only on crops they were supposed to protect (from insects), but on native bird species as well. House sparrows do not need cavities (nestboxes) to nest in but studies show that if a house sparrow is allowed to fledge from a nestbox, it will look for one when it is time for it to breed. That is why it is so important for people to monitor nestboxes when they put them up. In all my years of monitoring bluebird trails, I must say that the word timid is not a word I would associate with this beautiful, brave, determined bird. You will come to see this for yourself if you monitor your nestbox closely and let them teach you about their battle to survive. I promise that your heart will be broken now and then--Mother Nature will have her way--but you will also come to know just how precious their lives are and why we all work so hard to protect them.
