My sister just called me with a similar problem with the phoebe nest on her deck. The first thing that came to my mind was the cowbird. I'm surprised that no one has mentioned this notorious brood parasite. Even though the cowbirds most common host is the yellow warbler, the brown-headed cowbird often targets Eastern phoebes for its host. I've actually seen female cowbirds egg-dump phoebe nests. It's an extremely fast process. Now before people have evil thoughts towards the brown-headed cowbird, I have to say this: it's not the cowbirds fault... Cowbirds evolved following roaming buffalo herds around, and therefore developed a breeding strategy (brood parasitism) that allowed them to do so. The cowbird used to be an uncommon species here in the northeast, but during the 17 and 1800s almost all forests were cut down for farmland. Since cowbirds are an open spaces/prairie species, this is the perfect habitat for them. They also like edge habitat (powerlines, forest edges etc.) So, I told my sister to keep watching the nest for a cowbird chick. The young, a week or two along, should be larger, louder and healthier by far than the others. It's more agressive behavior as a nestling makes it sure that it gets fed at the expense (often fatal) of the others. So if the young in a nest all look and sound the same, chances are it "cowbird-free."

That's cool that they came back at all. I'm surprised. Usually any fledglings are just about ready to take care of themselves, but I'm sure, they continue to hang out with family/relatives! That is a really neat thing about nature that most people don't usally notice. But, we who love the birds ... notice and learn! PS: I'm happy for your babies!!!! ... tweet!

We had a phoebe build her nest on a security light above our deck, and after finding 3 or 4 nestlings that had fallen prematurely from the nest to their deaths on the hard deck below, we put an extra dog bed (large size!) underneath the nest, and sure enough, the next day I found a live nestling on the dog bed. I couldn't reach the original nest, but put a last years' nest in a margarine container, put the nestling into it, and pushpinned the margarine dish into our wood siding about 2 ft below the original nest on the security light, which still had 2 nestlings in it. Mama fed the rescued nestling in its improvised nest along with the rest of the babies, and I was fortunate enough to see it fledge a week or so later. So my suggestion: find something large & cushiony and put it below your phoebe's nest. :)

We had an eastern phoebe build a nest on a nest platform we put about 25 ft. up, under our eaves on the NW side of our house. The nest site was/is/should be well protected from rain and predators. Below is a gravel driveway with bordering shrubs, stacked firewood, raspberry patches and woods. Phoebe could regularly be seen hunting insects on the wing (sallying forth as phoebes do). More and more she was on the nest, apparently warming her eggs -- I didn't hear any peeps from nestlings (our bedroom widow is 7 ft. away and usually open). Around 8 days ago, I noticed a phoebe closer to the front of the house on our front railing and mountain laurel branch, then flying up to an unused ? robin's nest on another platform under the eaves and soffit at the front of the house. Again, this nest and platform seemed very well protected from predators and rain. At first I thought it was a different phoebe, perhaps making use of what looked like a robin's nest, recently built (25 days ago), but unused. A few days later, I realized it must be the gable, NW phoebe -- as she was no longer on her nest (on the gabled NW side of house about the driveway). What the? Egg or nestling demise? Owl? We haven't had an opportunity to check either nest out (rain and we'd need to get out a tall extension ladder). Our phoebe isn't even around the "robin's nest" now. No one is at either nest. Hard to believe that their were silent nestlings in the gable nest and they've already fledged. I didn't see any or much back and forth flights with food. Didn't hear any soft nestling twitters. Do any of you have any ideas? <beginning to wonder if house is cursed or weasels can fly or....>
