A Promising Start

Postby FarmerHarv » Wed Jul 11, 2018 8:10 am

Seeing as I was keeping notes and taking lots of pictures about my foray into becoming a Martin (and other swallows) landlord, I thought I'd start a blog about it. And then I discovered I knew nothing about setting up or hosting a blog, and that nobody would find it even if I did. So if nobody minds I'll use this thread to keep track of my journey, and with luck it might even be a source of entertainment and possibly some useful knowledge for someone.

The Early Years:

1995 - It all started in 1995 when my wife and I moved to the farm. There were always barn swallows nesting along the front of the house, and these provided quite a bit of entertainment as they swooped and fluttered around while we watched from the other end of the deck. Reading up on swallows led to learning about Purple Martins, and I thought I should build a Martin house some winter and see if I could get some to nest.

2016 - So 20 years later there was still no house, but I actually saw my first Martins over the yard in 2016, and did a lot more research thanks to the power of the internet. I came across Bob Buskas’ website, and ordered both sets of plans he had available for his house designs. I cleaned up the shop, gathered my tools and got ready to start building as soon as winter settled in.

2017 - Well, I didn’t get the martin house built yet. They were kind of forgotten as we spend most of our time on the back deck by the trees, and enjoyed watching the birds that came to the baths and feeders. I had never really paid too much attention to birds until now, and was surprised by the variety we actually had. There are Eastern and Western Kingbirds, Catbirds, Vesper Sparrows, Pine Siskin, Robins, Orioles, Goldfinches, House Finches, Brown Thrashers, Mourning Doves and of course house sparrows, blackbirds and the occasional grackle, crow and magpie. It was fun identifying them all, learning what they preferred to eat and which type of feeder they liked, and we were always trying different things to attract more and different birds all the time.

2018

Postby FarmerHarv » Wed Jul 11, 2018 8:11 am

June 1 - Move ahead to 2018, and the Martins were still without a home here. And the barn swallows also. After building a new farm house, moving off the old one, cleaning up the yard and getting rid of all of the old granaries and sheds, I realized the swallows had nowhere to nest. I ordered some nest cups and built them a shelter at one end of the shop, and while watching a pair check things out a Martin landed on a power post, which reminded me that I still had some unfinished building to do. I dusted off the house plans, looked at the mess I had turned the shop into and went and found something easier to do.

Image

As an aside, I did finally join Procrastinators Anonymous, but we never got around to having a meeting so it didn’t really help.

June 26 - Facing the fact I was probably never going to actually build a house, I contacted Bob about simply purchasing one, and drove over (about 500km) to his place to pick one up. And are we glad we did! Actually getting to see his setup, watch the Martins, and learn about nest checks and see some nestlings at different stages firsthand was well worth the trip in itself. Bob has been a great help since, patiently answering all of my questions and offering lots of great advice.

By pure luck and chance, it turns out that where we had placed the new farm house left an excellent area to place a martin home. The clear area was 75’-100’ away from the house, shop, trees and quonset, and being right in front of the verandah allows us to have an excellent vantage point from inside or outside the house.

June 28 - Once home I had the pole cemented in and the house up in a couple of days, and watched in dismay as the first sparrows started hauling grass into most of the compartments almost immediately. However, the first time I lowered the house to clean this out I had my first Martin come for a visit! He flew around chirping merrily, and then went and sat on the flagpole chatting all the while until I was done. As soon as I raised the house he flew right over and perched on it, and called away until 5 more Martins came over also. They all circled around for a couple of minutes and then flew off, but there were usually a few coming by once or twice every day after that.

Postby FarmerHarv » Wed Jul 11, 2018 8:12 am

June 29 - Started on my sparrow control regimen, which consisted of shooting them at bait sites I had set up, and almost immediately realized this was simply not going to work. Like many people I had never really paid any attention to HSOP, and once I really started looking I estimate there are a couple hundred around here. I started ordering traps (funnel, repeating, nest box), and let the sparrows build in the martin house so I could trap or shoot them once they established themselves in it.

July 2 - While waiting for the sparrow traps to come in the mail, I built a ladder trap that I remember seeing at a neighbours years ago, hoping to get started on HSOP removal right away. I had no luck at all with the sparrows, but did catch a hapless cowbird that drew the unwanted attention of a sharp shinned hawk. How the hawk managed to squeeze down to 2” and get into the trap is a mystery, but the cowbird didn’t survive to tell the tale.

Image Image

July 5 - Realizing that after we had taken down all of the overhead power lines there were very few places for anything to perch on, so decided to raise a 50’ long perch wire near the martin house. Went over to the old scrap machinery pile to get some big steel wheels to use as bases, and discovered at least 3 pairs of tree swallows had set up house in some old grain augers over there. I’ll definitely have to build some tree swallow boxes and set them up, as those augers will either be really hot or really cold depending on the weather and time of day.

After spending most of a day setting up the wire, sure enough the Martins came by to check it out. One sat on the wire, a couple on the house and two went and stood on the flagpole light. As the flagpole is quite a bit taller than the house or the wire, I added some 4’ dowels to it and it became an instant hit with everyone, and makes me wonder why I bothered with the wire. Oh well, maybe next year more will use it.

Percy's Place

Postby FarmerHarv » Wed Jul 11, 2018 8:32 am

July 6 - I notice that one (I’m guessing it’s the same one from the first day, I still can’t tell them apart) Martin is coming by very often every day, and sits on a porch and chirps and calls whenever he sees another of his group. When they’re out of sight he just sits quietly, but as soon as he spots another his tail jumps and he sings as loud as he can until they fly over. Sometimes he’ll fly out and try to lead them back, but mostly he just fills the yard with his chatter. I’m wondering if he’s getting enough to eat, being that he spends so much time sitting at the house.

Image

As he was the only one that spent any time at the house I saw that he never actually went inside any of the nest boxes, but just went as far as his shoulders and then backed out. I thought the holes were possibly too small, but Bob assured me they would go in when they were ready and not to worry.

This morning I was finally able to get a bead on the male HSOP that had nested in the house while he was sitting on a porch, and right after I fired the martin popped out of one of the holes. Turns out he could fit after all, and was maybe even spending the nights here. As soon as he was out he started singing away, and raced off to his group as soon as he saw them.

July 7 - I have named the lone occupant Percy, short for Persistent, as he spends almost his entire days trying to bring other Martins over to “his” house. And it’s been working. There were 10 overhead today, with 2 being the very very dark purple over all of a mature bird. When I was walking past the house to check the sparrow traps the whole flock started circling and chirping only 20 feet up, and unfortunately I was too slow to get a video of the performance. They have all spent most of the day over the yard, and a pair of them even buzzed the back deck where we were sitting a couple of times.

July 8 - Looks like the tree swallows have fledged out, as there were close to a dozen cruising around and over the yard today. The little ones would land in the trees in groups, and I had an adult try to take my head off as I was getting close for a photo. Also had a pair of barn swallows stop in for a short visit, and hopefully they checked out their new shelter while they were here.

July 9 - Apparently Percy’s bedtime is 9:00pm. For the last few evenings he has gone into #11 before 9, looks out the hole for a little while and then disappears for the night. He also brought a few short twigs and some green leaves over to the house today, but I didn’t see him take any into the nest compartment. Just practicing carrying stuff perhaps? Had a dark purple Martin at the house for quite a while today also, but Percy only seems to get really excited when the younger ones are nearby.

To be that far north and get some visitors that quick is a great sign. Keeping up with the HOSP will be a chore but is a battle toy can win. They have a home range and you can impact the local population. My first colony was located in the middle of farm country with a cattle and feed barn less the 200 yards away. As you can imagine the grain and straw really drew them in. The first year I got rid of over 100 of them. Each year after that the number got less and less and after about 8 years I was only catching/shooting 5 or so a year. I am fortunate enough that I can just walk out my door with a shot gun and get them as they fly off.
2018- 15 pair last count 49 fledged
2017 3 SY pair nested, 12 eggs total, fledged 10. 4 additional SY's stayed all summer but never paired/nested.
2016 1 pair fledged 4

Welcome and thank you for posting this great thread. Super pics and nice information. I wish you the best in the years ahead.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.

Yes, this HSOP battle is definitely going to be a grind. I've trapped over 30 females in funnel traps, but not a single male. Picked off 10 males, but they don't sit in one spot for long so it's a matter of patience and then quickness. Quite a challenge actually, but I have an insanely accurate Savage .22 that definitely helps. It puts SK Subsonic through the same hole at 30 yards, and shoots SK Match hollow point ammo inside an inch at 100 yards. It's expensive ammo, but worth it as it's almost like having a laser beam on a calm day. :)

I've ordered a couple of the Uncle Blaine's Repeating traps, and a bunch of Van Ert traps to install in some tree swallow boxes I'm hoping to build (yes, it may not actually happen) this winter so that should help take the pressure off before the martins arrive next year.

We live on a grain farm a mile from town, so there's probably going to be an endless supply of sparrows for as long as I live. With any luck most of the ones in town will stay there, but if I'm prepared I should be able to handle a few imports if I can get the numbers here down to something manageable. I might even try the shotgun...be like a round of skeet with very small fast unpredictable targets. Too bad I've always sucked at skeet.

Good read. Kudos for providing housing for so many types of birds! It can be addicting! If you're not careful you'll find yourself building houses for Chimney Swifts, Carolina Wrens, Northern Flickers, flying squirrels, butterflies, bees, and on and on.

If you decide to build a box for Tree Swallows the "xbox" is an excellent design. Tree swallows will also use plastic gourds. SuperGourd makes a nice large gourd with a 1.5"/3.81cm hole. I don't recall seeing it in PMCAs shop so you may have to purchase it directly from SuperGourd.com if interested. There's lots of good tree swallow info on here.

Thanks for the links! That Xbox looks pretty good, and quite simple also. Might have to make it a little bit bigger for the tree swallows and then they'll really have some upgraded housing.

And you're probably right about trying to attract more birds. I was on NestWatch and am amazed at all the different birds that will use different box types.

So it looks like the perch wire was a failure, probably because it was too far from the house and too close to the big trees. The kingbirds used it constantly, but the martins very rarely. I took it all down and simplified it to a single base with only 14' of perch wire, and moved it over to about 10' from the house. Now everybody uses it, including the little vesper sparrows. Percy still mostly sits on his porch all day, but will sit on the wire if there are other birds there.

Image

Speaking of Percy, he is practicing nesting after all. He's hauled a few leaves into #12, although I think he still uses #11 as his bedroom at night.

Great story and thread. Keep it going next year, I’m sure you’ll have a pair or two to post about.

I’m so jealous that you had one landing in the yard before you had a house up. Damn, that’s a good sign. I take it you have a colony or two fairly close by? I’ve only seen two martins in eight years here while playing the dawnsong loud seven hours a day. None in the last four years.

Nice house and yard. Keep it all going, you’ll have some pairs soon. You’ll probably be at capacity in 2-4 years.

That's something I was thinking about the other day...where are these martins coming from, and why are they here? Might be that my place looks nice and open compared to town, or maybe they have poor housing or landlords, or overcrowding and are looking for an alternative? I think the golf course has a few houses up but don't know how many or how well they're maintained, and it's only 3-4 miles away, and there are probably a few houses up in town that's 1-2 miles from here. We're only a half mile from the town sewage lagoon though, and it probably provides and attracts an endless source of different insects for martins and other swallows.

I definitely won't complain though, and I can't imagine the feeling of trying to start a colony and having no luck for year after year. Here's hoping next year will be better for you.

You're welcome. We added some additional floorspace and a perch on the top. Fishing line across the top and around the entrance have deterred HOSP thus far.

Percy is still...well, persistent. Every morning he hauls the whole crew over for coffee, and flutters from porch to porch making sure everyone is comfortable. Quite often he'll go into "his" compartment and chirp away from in there, and quite a few of the others have now gone into other compartments also, having learned how to squeeze through the SREH.

This morning there were over a dozen that showed up, and it was quite a busy gathering. Percy was in his glory though, and was never quiet or still for long while they were there. He is without a doubt the most entertaining bird I have ever watched.

I keep reading about how the martins are starting to head south already from colonies in the USA, yet Percy keeps bringing more and more over to his place up here on the 51st parallel. Highest count is over 20 at one time now, and I still have no idea where he's finding them.

Image


In other news, I did actually build some tree swallow/bluebird houses. Found the plans for what's called the Long Point box, and built 10 out of a single sheet of plywood. I really hope they take to them next year, as there can't be too many that fledge out of those hot/cold metal grain augers.

Image


And I think I might be making a bit of a dent in the local HOSP population. I have two Uncle Blaine's repeating traps, 2 funnel traps, two compartment traps and 8 Van Ert nestbox traps now. So far the count is 23 males and 114 females/juveniles that have been dealt with, and it looks like I've whittled away almost half of what was here a month ago. With luck and persistence there won't be more than a couple left by the time the swallows are back next spring.

Wonderful work on the boxes as well as HOSP control. If you have cavity nesters in your area that don't migrate, like the black-capped chickadee, they will use your boxes to roost in during the winter. We leave ours out year round but I need to make them more roost efficient — removable perches & weather stripping and a winter entrance. Another item on my never ending bird-related to-do list...

I'm at 227 HOSP dealt with now, and it's starting to wear on me a little. Just saw at least 50 more at the two little ponds we have (but only one male who sat in the crosshairs just a little too long) so it looks like there'll be no letup for a while yet. Built a repeating nest box trap and have it up and ready for next season.

Image

Pretty simple, although getting the balance just right is a bit of a challenge. Tested it with a couple of juveniles from the DRST and it looks like it'll work just fine. Just need to build the cage and I think I've run out of things to build for now.

I don't think we have any cavity nesters that stay here over winter. I'm actually not sure if I've ever seen anything here in the deep freeze besides sparrows, crows and magpies. I'm going to look into heated bird waterers in case there are any that brave the cold and stay here...if they do, they probably need all the help they can get.

Well, I guess that’s it. Percy and the crew have stopped coming around. :-( It was fun while it lasted, and gave us a taste of what we can hope for in the years to come. Very quiet around the yard now though, as it seemed like everyone left at once...the kingbirds, martins, swallows and robins all packed up and caught the same flight south apparently. There are just a few finches, some vesper and white crowned sparrows and a couple of hummingbirds left, and they’re pretty quiet for the most part.

The house sparrows are very, very quiet now though. Over 300 down, and there are only one very wary male and female with a couple of juveniles left that I know of. A large flock of 150-200 hits the wheat field around the yard every few days, and I’m guessing they’re from town as they never stick around or go for any of the bait stations and bird baths.

I did see my first ever starling this week, a juvenile at one of the bird baths. Very striking and distinctive bird, and I’m hoping to never see another one. None of the houses have an entrance big enough for them, so maybe they’ll just keep moving along. Heh, probably wishful thinking.

Wow - over 300 is super impressive! I don't have many but even one pair can be annoying and a problem to get rid of. Maybe the word has gotten out that you are a force to be reckoned with and they are all going to stay away from now on. :)

Yeah, it's kind of a crazy number. If I hadn't been keeping track I would've guessed it to be about half of that. Here's hoping you're right and I won't have to deal with this many again.

Image

A few interesting things I noted while doing this...

- The ratio of males to females & juveniles has been pretty steady at 1:10. I don't know if ~5 young per pair is high, low or average for this area and year.
- I only trapped 4 or 5 males. they're not so easily tricked by food as the others.
- Aside from one nest in an evergreen we could see them coming and going from the deck, I have no idea where the other 26 males are/were nesting. There isn't a single place in or on a building within 300 yards they can nest, so they're either using trees or coming here to eat from town or the neighbour's.
- Apparently sparrows must be buried more than 8-12" deep, otherwise a fox/coyote will dig them all up and make quite a mess.
- I should think about getting some cats for the farm. They could probably do a lot of this work for me. :)

That's a lot of sparrows and good job catching them, I like your aggressive approach. Sparrows can have 2 or 3 clutches a summer, so your ratio of 10 to 1 is not out of line. I had a lot when I started too, not as many as you, but now only have about 10 or so to deal with each summer. I hear them start their chirping on the first warm days in March when they start looking for nesting places. I did a lot of trapping when I started too, but now its mostly shotgun warfare when I hear them.

Setting up a winter feeder is another fun thing to do until the martins return. You may see many winter migrants come down from the north and keep you company. The birds that visited my feeder last winter include Redpolls, Chickadees, Nuthatches, Woodpeckers, Bluejays, Pine Grosbeaks. I'm sure there were others but these come to mind. I feed sunflowers and beef fat. The fat straped to a tree with hardware cloth is a major attractant to the woodpeckers. The nuthatches and Chickadees will eat it too.

Nice to hear of another prairie colony getting started. Your neighbour to the east in Manitoba.
