Well If you have ever seen TRES fledge theres no way a baby Blue will make it. I would almost opt to candle the eggs and if there is little to nothing there get rid of them. Is it possable to tell the difference between babies at hatching time? I would want to put them in the Blues nest but that could cause problems too. Lets think babies not eggs here. No way a blue can survive with a TRES Mom, overloading a Blue or having babies hatch days before her clutch could result in dead babies. Yikes this is one for Bet, Malinda or Cornell. Im still thinkin destroy the eggs so no babies ever suffer.

Awwww..so sorry to hear of this. That storm came through my yard too, and took one of my Bradford Pears down. It landed across my driveway, and luckily did not hit the house or our basketball goal. Gosh, it came through really fast. If you are not seeing them back at the house at all, then they have abandoned the nest. You don't need to wait the 2 weeks to remove the nest. Give it a few days, and when you are sure that they have abandoned, go ahead and remove the nest. Maybe they will build there again. There is still plenty of time.~~Angie

Because of the time frame, are you sure any that hatched didn't already fledge? I would count the eggs. It could be that none of them hatched, but maybe some did and fledged? If the eggs were fertile, they should have hatched weeks ago.

Lydia 1959...As far as it's known, from decades of research by the PMCA and other organizations, the Purple Martins in the eastern half of the U.S. nest only in man-made cavities, and near human activity. Since the times before Columbus they have "imprinted" on humans. The eastern Native Americans lured them to their villages and gardens by setting natural gourds on sticks and dead trees. They knew when the Purple Martins were near, the flying insects were kept at bay. There is a small scattering of PMs on the west coast, and they seem to be nesting in single family groups around piers. There was a lot of excitement when a colony was discovered nesting in drainage pipes under highway overpasses around the Sacramento area. Still, for the vase majority of the Purple Martins, and the entire eastern population, it's man made housing. You can see the problem since fewer and fewer people are offering, and safely managing, housing for them. The PMs, along with our native blue birds, started declining in the 1950s and were fast approaching endangered status. The main causes were lack of housing being offered to them, loss of wooden fence posts in the case of the blue birds, and the explosion of the imported, non-native English House Sparrow that will kill/destroy any cavity nester, its eggs and its chicks, that it can find...PMs, bluebirds, chickadees, woodpeckers, nuthatches, etc. all fall prey to these non-natives. So, loss of habitat, explosive numbers of non-native competitors, and a lack of well-managed housing not being offered is the main culprits of the decline of our native cavity nesters. I wish you could come visit. I sit under the feeder tree each morning with my tea and listen to the beautiful chatter, chortles, and songs of the PMs. They're here for such a short time, but I try to enjoy them enough to last the rest of the year. They travel to and from southern Brazil each year to raise their families. They come back to the same colony each year. They are magical!
