Two ASY male purple martins arrived on March 10, 2019 this year. This year's arrival is more back in line with my first 10 year average arrivals.
In all the years past, my martins had also arrived with the tree swallows, however, this year, a male tree swallow had actually arrived a week earlier. During the last few days the tree swallows have been swarming the nest boxes in the fields and my blue birds are not really thrilled with their arrivals.
They are such happy, cheerful little birds and love to fly up high with their bigger cousins. I was going to remove this perching pole this year, but since they seem to like it so much, I may have to leave it...I don't want to upset my fabulous sentries!
This year, I'm making more changes. A landlord decided he wanted to retire his colony, so I bought some of his equipment from him - namely another Super System. It is so much easier to do nest checks with the extended cages on these systems than it is with the round Deluxe gourd rack systems, so this year, I'm removing one of the Deluxe systems and by adding 4 more gourds to each Super system, I'll still be able to offer 84 gourds and my nest checks won't be so painful (literally - it was death by a thousand scratches in the round racks).
So, with this system, I'm designing the cages in the same way - since they work so well on the other racks. I'm extending the 4' gourd arms by adding an 18" aluminum angle arm. I drilled 2 holes to mount the extensions to the main arms, with another 2 holes on the very end, where I can mount the cage wire.
Then, I have laid a 6' piece of aluminum angle arms from corner-to-corner. We drilled holes in each end, so I can anchor them down with tie-wraps. This helps support the top cage wire, so it doesn't sag, and these arms are super-light.
Since I've removed one of the Deluxe round racks and I wanted to keep the same number of gourds, I added 1 gourd per arm on each rack, so I'm still at 84 gourds. For the end gourd, I replaced the straight arm with a 45 deg. arm, which effectively points the end gourd back inside the cage.
For this Super system above, I just replaced all the arms with the extra long arms I had purchased from Hilltop and have made it a perching rack / feeding tray / oyster -egg shell feeder. Bob was tired of seeing me stand on my 4-wheeler to try to fill the other tray on my old post, so we converted this one.
For now, I only have 10 martins here, so I'm taking my time and making sure I have everything the way I want it. Lesson-learned: it is super annoying to get into the heat of the summer with jumpers and not be able to easily put them back into their nests. This Great Horned Owl has made my life more difficult but as she has learned and adapted, so have I.
I'm also keeping the Deluxe gourd rack that I took down - you never know, I may change my mind when I retire and put it back up and expand my colony, but for now, I'm pretty happy with offering 84 gourds that are 100% protected from the owl, yet still being able to perform nest checks.
Lookout 2019 - here we come!
