Ontario Breeding Bird Atlas tip from the best atlas region: You may be strolling along, enjoying all the birdsong in #themighty24 and even identifying some or most. You likely know that songbirds are able to perform these vocal aerobatics due to their specialized "voice box" called a syrinx: their trachea splits into separately controlled bronchial tubes. But instead of leaving those songsters as possible breeding birds based on only hearing them sing, try to catch a glimpse of that bird. You might be pleasantly surprised to see that little Chestnut-Sided Warbler you are hearing is actually singing WHILE carrying food! The structure of the syrinx enables them to switch from one side to the other without taking a breath, or having to drop their food! You've just birded in "Atlas Mode" and as a result of your careful observation, you are able to actually CONFIRM breeding!
