Hey guys I have a ? I have read a lot about site fidelity. I had 1 pair last year 5 eggs 4 fledged. What are the precentages that my pair will return this year. I had several sub adult males and one other female that would stay over some nights. Very excited for this year!!! Have a great year everyone. JHCOX Heiskell TN

Chances are excellent provided the birds survive the migration. Even though they will be adult birds they probably won’t be among the first to arrive in your area so if you see scout reports popping up around you. Don’t panic.

Thanks Tombrake I sure hope they make it back it took me 4 years to get them to take to my site. I hope they bring some friends with them. I’ve have 30 cavities up. But I have another 60 or 70 more stored in my barn that a friend gave me. Don’t want to put them up until I need them. It would be nice one day to have s large colony like that. Best of luck the season and thanks for the help and support. JHCox Heiskell TN

I think you will have good luck increasing the colony this year. Sounds like you are ready to go. I’m not too far from you , in in Abingdon va. Second and third year went from three to eleven pairs then grew steadily after that. Good luck. I’m looking for my first birds to arrive around March 10 but it’s about early April before they return in any amount and mid to late April when the majority are back. Second year birds arrive here late April and later.
Of course dates are general and earliest ever I had a first scout was February 25.

Jhcox,
Despite the one pair you sound like you had lots of visitors and your pair were sucessful in fledging. It is a long journey for them but id say your chances were pretty good this season for their return. Always look to improve the site, or homes each season and the birds seem to reward us. Sounds like you have a good site and are offering quality housing. It is exciting and the wait for a colony is probably over for you, bet your numbers jump up.
I wish you all the best this season!

My first pair was successful in 2017. Waiting for them to return in 2018 was quite stressful. They did return and raised another successful brood. Another pair joined them and was also successful. Fledged 12 total. So this year I am now waiting for two pair and my son and I have bet as to how many total pairs we will have this years. He says four. I'm optimistic at 5 or 6 only because so many here have posted a jump in numbers after the 2nd year at their colony.

Mine should be back soon here in North Texas.

Good luck to you.

Thanks everyone for the words of hope and encouragement. I pray that make it back safely and bring friends. And I forgot to say the property across the street is turning into a subdivision that stinks but the good part is that they built a run off pond so now I have a pond on both sides of my property now for the birds. Hopefully that might make my site a little more appealing to them. Thanks again and god bless everyone with a great year.

That first few years getting them to return can be frustrating. Like others have said, assuming they survive the migration they will come back to your site. I can't remember the percentages but a big percentage of birds do not survive the long trip. That is part of the reason that each pair of martins can fledge 3-7 young each year but the populations are not growing by leaps and bounds every year. Part of it is just older martins dying of old age but I would guess the number of martins that live for years and just die of old age is a lot lower then the number of martins that don't survive the migration. There are predator attacks, environmental factors, etc. all of which take a tole on the population each year. I know the number 5 years gets thrown out a lot as an average to get started but I started 2 colonies and both times it took 5 years to get "established". Both locations I had 1 pair some years a couple pair hear and there and then none the next year. I hope the best for you this upcoming season.

Thanks flyin lowe for the info. This will be year numer 4 for me. I have had the one pair and 2 subadults that were here all of last season. But I did have a lot of visitors sometimes as many as 8 or 10 would come in for several days checking out the site subadults and another adult pair came around a lot last year. Hoping for the best for me and everyone else this year. Happy martin season. JHCox

I wish I could find the study, I can't remember if it was in one of the PMCA magazines or somewhere else but it stated that on average you need to have 6 pair to ensure you will have returning birds the next year. As always with mother nature, something drastic could happen and wipe out a whole flock. But typically, once you get to six pair odds some of them will survive the migration.

I’m far from 6 pair but maybe I’ll get lucky and they’ll make it back.

It seems the first ASY that makes it at your place is the key. They can really draw a crowd. At my first place I had a SY male spend the season in a cavity and never attracted a mate. The next year he came back to the same cavity and I had 5 pair that year. 2 years ago I had some SY’s and last year was my first year at this site with Asy’s returning and I ended up with 15 pair.

I hope I’m that successful this year at my sit. But would be content with the pair I had last year. But thumbs up maybe they will bring a couple back with them. I love to watch the scout map fill up with those purple dots and move up the map. Should be showing up in the east TN area in about another month and a half. JHCox Heiskell TN

In 2001 I started out with a T-14 and four gourds, and was able to attract one solitary pair. It was the first year I put out any housing for PM's so I felt quite lucky to attract a couple. They successfully fledged five or six young, and since that year, my colony has grow exponentially in terms of numbers. Today I have a single satellite-dish gourd rack with 56 gourds and plan to add an additional level to increase the number to just under 80 or so. Good luck this year, as I'm sure you'll see PM's returning to your site now that you successfully hosted a pair!

Thanks for the support Maxxwlf. I really hope it does. I really like those old repurposed satellite racks. I have gone down to Rainsville Alabama to see what is said to be the largest Purple Martin colony in the world on Jerrel Johnson’s farm. If you or anyone else that reads this gets the chance to go down to see it it is amazing. 80% of his gourd racks are made from old satellites.

Actually I think the number is 10. The likelihood of returns is 100% if you had at least 10 pairs the previous year. Not saying you're not getting a returning pair this year, but the odds is 100% if you had 10 pair last year.

Thank you for the information Tor. I sure hope that they come back then maybe I’ll make my way to 10 pair. But for now I’ll be very happy if I do get the one pair from last year. Thanks again JHCox Heiskell TN
