Just about when "all was well" early on, and egg laying was in full gear......everything changed here.
Repeated cold and rain pretty much put a halt to egg laying and I fear the eggs that were laid probably couldn't handle multiple nights in the low 30s.
We had many days of wind and cold rain with temperatures never getting out of the 50s.
The good news is I only found one dead Martin. The bad news is many of these clutches of eggs will likely not hatch or the hatch rate will be very low. .
I went through many pounds of freeze dried mealworms and a lot of Nekton I powder in the past few weeks. Last night 33 degrees, the night before 34 degrees. That's too cold for incubated eggs.
Yesterday it finally topped 60 and the entire colony was away feeding instead of tending their nests. This is more typical of early "prenesting" behavior and early season survival behavior.
Finally much warmer going forward.

A very rough May for Martins in PA

- Martin Colony History: First pair in 2009 after 28 years of trying. 3 pairs 2010, 17 pairs 2011 and 35-45 pairs since. Many additional colonies are now springing up around mine in an area once completely void of Martins. I offer 50 compartments at my site consisting of primarily Excluder II gourds on Gemini racks. Also a wooden T-14. I utilize electric fence type predator guards on the base of the poles. Supplemental feeding is crucial in maintaining my colony. I platform feed throughout the season as needed. My site tends to be a stop over point for additional birds as they migrate further north.
Supplemental feeding plays a major role in Western Pennsylvania. Finally got my 1st pair in 2009 after 28 years of effort. The colony has grown quickly to 45 pairs that I care for. Many new colonies have now sprung up around me in the past few years as well. Where there was none.... there is many.

It's been a tough late spring weatherwise for martins and other swallows along the northern tier of their US breeding range. I suspect total overall reproductive output will be much lower than average for the segment of the purple martin breeding population in the northcentral and northeast US this year.
It's good to hear about martin landlords across the country making the extra effort to feed martins during such inclement weather...it does make a difference.
Keep up the great work!

Tough indeed. Hopefully it will make the PMs stronger in the future. Keep up the great work!

- Martin Colony History: Several colonies with in 6 mile radius.
Have had visitor every year 2014-24.
Two large trees removed in fall 2024 and moved T-14 to a more open location.
2025- 1 SY pair. Fledged 2.
Hi Doug. I’m in central PA, and spoke to a long time land lord, who lives 2 miles away, yesterday. He has 6, full, T-14’s. Based on your post, I asked him if he had any eggs laid prior to the cold snap we experienced a month ago, and he said he did not. We are typically a couple weeks behind western PA. So maybe this area was fortunate to be later again this year.

2014, 1st year-a few lookers, no nests
2015-23. Visitors each year. But no pairs.
2024- most active year. 2-4 SY male’s hang out most days.
2025, 1 SY pair. 2 eggs, 2 fledged!! Other martins visited daily.
Still eliminating starlings and sparrows.

Hey Doug. Did your early eggs hatch? I know of a landlord about 6 miles away. He has a full 18 gourd rack. Only one SY pair. But his egg count only averaged 2.5 per cavity.
