Re: THOUGHTS ABOUT ROOSTS & FALL MIGRATION==TX

Tdart, There is probably not a lot to be gained this late in the season.. For you, nest season is your first opportunity. I am not sure how much opening cavities will help you this year, but no harm in opening them as long as house sparrows are NOT trying to claim the housing, or starlings are hangi...

Re: Second Clutch Possibilities ?

Bill, I have authored or co-authored with Texas landlord Tony Frederickson several articles for PMCA's Update magazine pertaining to second broods. Our first article was published in 2006 and followed by my article in 2009, after identifying 3 banded males involved in raising two broods with females...

Re: New to purple martins

Welcome Birdgirlnerd, Texas is a big state with many diverse regions. It would be helpful to know what area you are in; what town(s) or city you are in or near. You can go to the Research tab on the PMCA main website; look at the Scout Arrival Page, and possibly identify some other landlords nearby ...

Bird, Addressing the questions in your post I would say talking to BioJoe at PMCA would be as good a place as any to investigate some type of tracking project. And I agree with Bill Wenger's comment regarding the expansion of the MOTUS tracking system, which likely is more cost effective and will se...

Re: THOUGHTS ABOUT ROOSTS & FALL MIGRATION==TX

Hanover Bill, A couple of thoughts having visited the Erie roost two times. First, the Presque Isle location has been utilized as a pre-migratory roost for many years and offers an abundant food source to sustain the large roost, in addition to being a prime seasonal feeding area. It attracts martin...

Re: From Colony to Roost, What do they do ??

Bill, Just posted a new article with a lot of information about roost formation and migration. Although timing will be later in the North than in Texas, the dynamics will be similar. Always glad to see the success you have achieved in creating a purple martin colony.

THOUGHTS ABOUT ROOSTS & FALL MIGRATION==TX

Reading through recent posts there seems to be some confusion about the dynamics and timing of migratory roosts and migration timing of purple martins nesting in TX. During the nesting season adult martins, particularly ASY males will establish a local roost in the area, often over-nighting at the l...

Re: Cresent Versus Modified Excluder Entrances?

Dan, You can find a picture of the modified excluder on PMCA main website in their store at the Excluder Gourd section. The ones I used were built into tunnels incorporated in natural gourds. As far as the excluder gourd owl guards, we have not used those. IMO, owls chase martins out of gourds in th...

Re: Cresent Versus Modified Excluder Entrances?

Dan, All three entrances are starling restrictive. The excluder entrances are the most restrictive due to the built in "pips" that restrict a starling from turning sideways to defeat the entrance. The excluder entrance offered with excluder gourds is the excluder 2. It is the latest design and is th...

Re: The Lone Chick seems to be pulling through.

SueP, It is normal for parents to reduce or essentially stop feeding nestlings as they approach and reach fledge age. This is done in an attempt to encourage them to leave the nest. If the chick you are concerned about was with a second chick it's possible the other chick has fledged and the parents...

Alberta is in the far northwest corner of the "Eastern" purple martins' range and there are some great landlords in Alberta.

Re: Nest check yestrerday, three gourds with mites (and a question)

A small amount of sevin sprinkled around the perimeter of a nest, or tapped underneath it, will kill the mites within 24 hours. The suggestion that I would add: If you are treating a gourd rack or a house, if one cavity has mites assume that all other cavities do too. Active mites are capable of tra...

Re: 11 egg clutch

Mike, Nearly every season we see posts on different forums asking about excessively large clutches of eggs found during a check (eight or more). In nearly all cases these are the result of poor weather, poor incubation (weather related or eggs getting buried among excessive nest material) or the pre...

I talked to Mel at Hilltop Specialties today to ascertain the status of the new WEP. He says they have been manufactured and are available for purchase from PMCA.

Re: PMCA Wing Entrapment Protectors heads up....

IMO, if the new design is 1inch thick, martins should be able to navigate it. I might install them 1/32-1/16 inch above the entrance top to make their entry easier. The UHMW plastic is so slick. A good material they can sail through. Thanks, btw, for identifying the material. I really like it; howev...
