Two white eggs, no green leaf? Please see pictures. Is this normal?

Are there white feathers in the nest? That looks like a tree swallow.

Picture looks like a tree swallow. Dont have them here, so don't know what their eggs look like.
A good house sparrow is a dead house sparrow.

100% a tree swallow. They shouldn't be in your PM housing as they will run off any PM's. There are some good links in here that I followed to a tee and I have Blue Birds, Tree Swallow, and PM's all within 40 yards of one another. I set a single small natural gourd with 1.5 inch opening about 30-35 feet away from my PM housing and on a black steel pole 6 feet high. The Tree Swallows too to it naturally more than the PM gourd rack. They have nested and hatched their young (day 13) and peacefully coexist with my PM's! Good luck.

Martin Colony History: First year

I guess my year is done before it started. This is year #2. Issues: I completed weekly nest checks just like last year. I did kill sparrows, similar to last year when I Had one successful pair. This year the PMs were fighting for 3 weeks I had no idea what to do. I had barn swallows and did not kill them, because they eat bugs also. I did throw out 4 white eggs, without any green leaf. Extremely disappointed.

Martin Colony History: 2010-2014 located in Slidell LA. Gourd rack with 16 gourds. Max of 2 pairs during this short period in Slidell. Plenty of fledglings.

2014-present.. moved to Broussard LA. Same Gourd Rack but added a 6 room house (modified from a 12 room)

2020: after a long drought of nothing, 4 pairs and 4 nests, 23 eggs total.
6 fledges.

2021: 9 pair, 47 eggs
36 hatchlings
30 fledged

2022: about 12 pairs.. many eggs, all fledged.. only had one hatchling die.. probably because of our schnauzer. :(

2023: 16 pairs. So far about 60 chicks with about a dozen eggs to go.

2024: 13 pair. About 60 eggs
2025: 14 pairs .. 69 eggs.

Why throw out the eggs? If they are tree swallow eggs, I’d just leave those alone. You may not get martins, but tree swallows are good guys as well.
I’d settle for TS over HS any day. :)


Maybe try to lure the tree swallows to some gourds in another spot with proper tree swallow holes. try to get them to go there and then for next year maybe they won’t try to settle in the martin housing. It’s something you can get going now to prepare for a better start next year.
