I'd never paid much attention to swallows until this spring. We noticed a loner in the yard last Friday for a while then it left left and we haven't seen any since. I thought they must have scouts like with Martins so I googled it . Supposedly the lead swallow is an "early bird" and the lead Martin is a scout. I'm skeptical.
"Some folks think the early-arriving swallows are “scouts,” but the idea of sending advanced scouts is not really the birds’ style. Remember, we are talking birds, not the U.S. Cavalry. A swallow isn’t going to fly hundreds of miles north, check out the situation and then fly all the way back to tell the other swallows the coast is clear. The early birds are just early birds and that’s all."
Purple Martin “Scout”: The term scout is given to the very first martin(s) observed back at an active colony site each year. Scouts are the oldest individuals in the population, who migrate north as early as weather allows. They can be either male or female.
No Orioles yet , They usually show up on a rainy day so theres still hope. What they had to say about Orioles, early birds VS scouts. Scout birds are out at this time of year looking for food and homes as other orioles migrate north for the summer.
