Photos Of My 2015 Purple Martin Colony

Our two personal purple martin colonies, mine and my neighbor Bobs’ site, are doing very well and more martins continue to arrive every day it seems. I believe I have between 200 and 250 pairs of martins in residence right now and the numbers continue to increase as more ASY and now SY martins arrive. Bob probably has around 150 pairs. There is all of April and most of May to attract more martins.

We started off this season with many fewer martins and the late February and early March terrible weather did adversely impact many martins in northwest Louisiana. The martin migration was slow but has now picked up considerably. I am not sure if we will match the martin numbers we had last year but things have greatly improved and so there is a good chance we will. We usually attract between 500 and 600 pairs of martins each season to our two personal colonies.

For 2015 I have 404 cavities: 324 plastic gourds and 80 Trendsetter compartments. I am using 206 Troyer Horizontals with cling plates and with tunnels/porches, 50 Troyer Verticals with tunnels/porches, 32 Super Gourds, and 36 Excluder Gourds. I have five Trendsetters: three 12 room houses; one 16 room house; and one 28 compartment system.

Nest-building is going full steam as the females bring in mud and the males bring in dry oak leaves. I suspect there will be some nice mud dams in both gourds and houses this season!

Today April 2, 2015 several SY male martins succeeded in securing gourds in a new K24 system I had erected mainly for the SYs. I believe we will be seeing many more SY males arriving in the next few weeks and there is still plenty of room, but they will have to fight viciously the dominant ASY males which are controlling multiple gourds/house rooms.

April is usually the deadliest month for migratory Accipiter hawks and merlins (small falcons) to attack our two colonies. The attacks can occur at any time during the day as the raptors pass over and are attracted to the hundreds of vocalizing martins. I have witnessed NUMEROUS attacks by these raptors on our purple martins since establishing my colony in 2005.

Because more martins are arriving daily there are current residents at our colonies nearly all the time. These martins are protecting their territory from the new arrivals. Many savage battles are occurring with martins rolling on the ground after falling from the gourd racks/houses. Sometimes the combatants become drenched from early morning dew and one or both will be unable to fly until they dry out.

Gangs of ASY male martins are now brutally attacking and raping female martins that are trying to gather nesting material or eat egg shells or pursuing females and assaulting them in flight. These attacks are however MILD compared to what will happen soon when the females are getting ready to lay eggs. The males KNOW when a female has an egg inside her and it is absolutely HORRIBLE when a gang of males pounces on a female and beats her to the ground. I have seen over a dozen males completely covering a female in a violent orgy as each male tries to rape her. They will rape her until she can’t fly and I have seen them break female martins’ wings and peck their eyes nearly out. Every male wants to spread his genes and the only way he can do it is by fertilizing a female. Each season some females are seriously injured or killed by gangs of ASY males and I have rescued many that have been beat down in hayfields by sex crazed males. The females can’t fly because they are soaking wet from morning dew.

Here are some photos of my martin colony. These show various sections of my colony and the last one is a panoramic photo of the entire colony.

Spectacular site. Didn't like hearing about the bad boys attacking the ladies tho'. Nasty. Steve...could you tell me what you are using as predator guards on the poles. It looks like netting.
Thanks and keep up the great work.

I am glad folks like the photos of my martin colony!

My colony has changed over the years. I initially had many natural gourds but converted all those to plastic ones and the martins readily accepted the change. I consolidated many of my smaller gourd racks into fewer larger systems and the martins had no issues with the change. And I replaced all my other aluminum martin houses with all Trendsetters and the martins didn't mind at all!

The predator guards are net traps constructed from bird netting. These traps will catch rat snakes that may try to climb the poles. We don't kill any rat snake caught in the traps. The snake is removed and taken for a ride in country! Though rat snakes do eat birds, they also eat rats/mice and are beneficial.

The arriving SY male martins are trying real hard to move into the gourd racks and houses. There is plenty of room but dominant ASY males try to control as much territory as they can and these males fight any other male that tries to take an empty cavity.

I'll post more photos later on.

Thanks again for the kind remarks about my martin colony!

Always a treat to see pictures of your humongous site, Steve. I see that you use the netting but can't tell if you also use the traditional predictor guards? Also wondering if you have any theories on this unusual martin season? Where are they? Enuf questions! Thanks for sharing your martins with us.

Steve - thanks for the info on the netting. Glad to hear you don't kill the rat snakes - up here in Ontario they are on the endangered species list. K

I just got up and I deffinetly remember my dream. I dreamed I got martins and they were raping all the females and I had to call John Miller to come and help! Then when he got here a hawk was after them! I am just wore out and just got up! :lol:

Hey Jody,

I am glad you like the photos.

Currently I only use net traps to thwart rat snakes. I have thought about adding a baffle for possible raccoon predation. Raccoons tend to stay in the more wooded areas and we have coyotes that will prey on raccoons if the coyotes can catch them in the open.

Regarding the unusual martin migration this year...

The weather in North America probably has little impact on the wintering martins down in South America. Martins may have evolved a migration behavior over thousands of years and this behavior is possibly encoded in the martins' DNA. When it is time to migrate north to their breeding colonies, martins may respond to intrinsic messages in their genes based on a biological time table and the martins head north.

But why would the martin migration seem to be "late" or "slow" this season? I do know there has been a disastrous drought in southern Brazil where some martins possibly migrate and winter. I wonder if this extreme weather condition may have impacted martin migration patterns in some way.

The exciting geo-locater research being done by the PMCA is providing more information about martin migration behavior and as more data is collected over time then some of the mysteries of martin migration can gradually be solved. I am looking forward to reading more about geo-locater research being conducted by the PMCA!

I hope you have a great martin season!

Very nice Steve, it looks like the average spacing between your poles is about 14 ft, is that correct? Have a great season.

Hey Ray,

My gourd racks/houses are spaced anywhere from about 12 to 20 feet apart and 14 feet is a good average. Bob, my neighbor, thinks my stuff is TOO CLUTTERED! He has his housing in a more "linear" set-up with about 15 to 20 feet between the systems. Both methods work fine.

Hey rrmartins,

I am glad you liked the photos of my martin colony! Thanks for those kind remarks. I hope you have a great martin season, too.


Short update...

At around "high noon" today all of our martins started screaming the danger call and I knew what that meant! Martins were scattering and others were climbing as the Grim Reaper was charging through!

Bob, who is hard of hearing, heard NOTHING! But did see the martins flying wildly.

Well, my single decoy martin on about a 13 foot tall pole located about 100 feet south of my martin colony deflected a female merlin (small falcon) from any real martins and she hit that decoy several times! She would climb up, dive down and hit the decoy! After several tries, she took off at a great speed and headed north with a bunch of male martins pursuing her!

April is the main month for Accipiter hawk and merlin attacks on our colonies. We still have weeks of this and martins must be ever vigilant.

JRS/Tmoe58,

Thanks for those kind remarks! Yes, we have our hands full with our two large personal colonies and five satellite sites. Each season we probably have 700+ pairs of martins in all our colonies and raise several thousand fledglings.

Short update...

More SY male martins and even ASY males are arriving and fighting to gain territory. Fierce battles are occurring!

Today at around 4:30 pm Bob and I were getting ready to go to our nearby satellite martin colony at the local garbage dump. Not a glamorous place for a martin colony but the martins get a lot of viewing by folks dropping off their garbage!

Just as we were about to leave I heard the screams of terror coming from martins at my colony. Flying at about a foot off the ground was a large mature female Cooper's hawk and she streaked through my colony and kept on going through Bob's while we watched from about 50 feet away. I did my customary hand clapping and hollering and that did distract her as she flew away into a nearby woodlot. She was unsuccessful but her attack sent all of our martins high in the sky where they circled and screamed.

Every day now our colonies may be subject to attacks by migrant Accipiter hawks and merlins until about mid-May. April is the worst month.
