Favorable Weather in the Coming Week
Peak spring migration is approaching in the southern latitudes of the US. The northern latitudes should see many new arrivals with favorable weather conditions coming up. Get your binoculars ready!
Dear Journey North Readers,
It has been a very active week for weather! The two systems I mentioned last week really restricted migration, but in between birds did some moving. Ovenbirds, Yellow Warblers, White-eyed Vireos, and Orchard Orioles were seen in New York. Tree Swallows, Blue-gray Gnatcatchers, and Louisiana Waterthrushes were able to make it to Vermont and New Hampshire. In Ohio, Illinois, and Michigan,Tree Swallows, gnatcatchers, Prairie Warblers, and Yellow-throated Warblers made their first appearances. Here in Chattanooga, I saw 2 Blue-winged Warblers on Saturday, along with my first Prairie Warbler, Ovenbird, and Summer Tanager. Red-eyed Vireos were more numerous than the previous week. Some of my colleagues from other parts of Tennessee also saw Blue-winged Warblers, as well as Wood Thrushes. On Saturday and Sunday, a very powerful cold front moved across the country. I expected to see lots of sightings from the Gulf coast, but not many people got outside. For those that did, the storms did force some birds to land. Things were blue in Louisiana, with lots of Indigo Bunting and Blue Grosbeak sightings. Alabama was red, as Scarlet Tanagers and Summer Tanagers were numerous. There was not much activity reported in the western US; mostly Violet-green Swallows, Vaux’s Swifts, and Black-headed Grosbeaks.
Will this week be better? If you look at the weather map, you see it is dominated by high pressure. In the eastern US, those high pressure areas are very strong, providing north winds yesterday (Monday), today, and tomorrow. Birds will not be going anywhere for a few days. Out in the Great Plains and Rockies, birds are now on the back side of those high pressure areas. Migration should resume with clear skies and southerly winds. By the end of the week, the eastern US will have southerly winds after the high pressure areas have moved on, allowing for migration to continue. There is another high pressure area that has moved in off of the Pacific, bringing northerly winds (although not as strong as in the east) to the western and southwestern US. Birds in those areas will stay put for a day or two before being able to resume their migration.
Overall, the week looks pretty quiet weather-wise. People in the northern US should see a lot of new arrivals. In the southern US, the next two weeks should be the peak of spring migration. There will likely be good numbers of species that have already been seen, as well as some of the late season species such as Swainson’s Thrushes, Blackpoll Warblers, and Yellow-billed Cuckoos. Take care.
