Re: Texas Hummingbird migration

It is complicated. As days shorten, some birds will be stimulated to molt after the breeding season is completed and before migration. The decreasing photoperiod affects the pituitary gland, which is also known as the master gland, which releases various hormones. In the spring, increasing daylight ...

Re: Texas Hummingbird migration

Still have 4 hummingbirds squabbling over feeders here in Central Wisconsin today. Weather supposed to be warm for the next week. We will see if they hang around.Days are getting shorter. Daylight effects on their pituitary glands can have an effect on migration that overrides temperatures. We will ...

Re: Texas Hummingbird migration

Just watching several fight at our feeders. Fewer here but still protecting the feeders. I place them on opposite sides of the house to keep males from dominating as much as possible. Ours are Ruby Throated.. Orioles still feeding at the grape jelly. They will be gone shortly before the hummingbirds...

I went high tech. I use an indelible marker to mark my gourds right under the porches. It lasts for a couple years before it fades.

Re: Updates from north of Toronto, Canada

Gotham, My experience with unmanaged martin colonies is very limited. When I first attracted martins I was happy to just get them. Luckily, several nests fledged young and I was on my way. All that knew for sure was that during the process of cleaning out the cavities, I found unhatched eggs, dried ...

Re: Updates from north of Toronto, Canada

Gotham, Have you considered offering to help manage the martins on the nearby property? I do not know the situation but if doing a few nest checks/ replacements on that colony could fledge more martins, you may be successful in establishing an active colony. As I have explained here on the Forum, a ...

Re: Do SY's return to their birth colony?

Gotham, The best attractant is live martins. I played both Dawn Song and Chatter for YEARS at this site without success! Early in the establishment of a colony, when it seems that we may be more cognizant of everything that is occurring, a lone male martin will leave the colony and return with a fem...

Re: How many is enough?

Billie, Here is my experience.It took a while but I persisted. In many cases, one pair of martins is all it takes to make someone happy. I still remember that first SY pair. 12 cavities is a reasonable starting point for a potential martin colony in a good location. We often read here of hopeful mar...

Re: Do SY's return to their birth colony?

I just checked my records specifically for SY returns. We banded 77 nestlings in 2014. The next year, 5 banded SY birds returned ( 2 female and 3 males.). That is a 6% return of SY from that hatch year. Incidentally, red banded male #05 returned as an SY and returned in 2016, 2017 and 2018. SY femal...

Re: Do SY's return to their birth colony?

Billie, In the past 6 years, I have had 14 martins banded as nestlings at my colony return to nest here as adults.That is about 5% of the total numbers banded. However, if estimates of high juvenile mortality are as high as even 50%, that percentage could essentially be a 10% return of surviving nes...

Re: Small colony results with active managemen- Best practices

Gotham, Correct on both points. I use pine needles from white pines collected in the Fall when they cover the ground. Make sure they are dry and store them in a trash bag. I placed a good handfull in the cavities after dusting the inside with carbaryl (Sevin), or any dry powder insecticide that is s...

Small colony results with active managemen- Best practices

After 25 years of trying and several years of actually attracting martins and allowing nature to take its' course. I became discouraged that there were relatively few eggs that resulted in fledglings. How many fledged? I have no idea. How could I? No records, few nest checks and haphazard vermin con...

Re: MITES! I had no idea!

Additionally, immediate nest replacements will quickly knock down the population as long as the nestlings are not near fledging.. You can then add Sevin(carbaryi) under the new nest material. In future years, at least two nest replacements at day ten and another at day 20 or even more frequently can...

Re: Here is my set up that has martins thriving in a small residential yard.

Apples to oranges. Active compartments actively managed is key. Providing cavities and attracting martins and then providing lilttle oversight does not permit one to document results. If success is defined as having a nesting martins, providing cavities, attracting martins and cleaning out old nests...

Re: Here is my set up that has martins thriving in a small residential yard.

Do you actively manage your colony with nest checks and nest replacements? Your site looks fine. Obviously, the martins accepted it. Especially in areas with lower martin populations, active colony management can significantly increase the local population and produce martins for other potential col...

I've completed most of my first nest replacements thus far.I did three beginning on day 7, then day 14 and then day 20 last year.

Wisconsin's martins are at least a month later in arrival than those in the South. Fledgling will be sometime in mid July and later. I have had parents still feeding young as late as the beginning of September. In this case, it was the result of a second successful nest. That year, the ASY pair rais...

Re: A gang of martins?

With the recent storms, it is possible that their colony sustained damage and they are looking for new housing. They would have to be adults as it is too early for any of this year's young to be about. My oldest nestlings are just 9 days old. Coincidentally, I had a new pair of ASY here yesterday af...
