Ruby-throated hummingbirds should make a dramatic move northward in the week ahead. Bad weather has been holding them back.

Highlights: Slow Progress
Ruby-throated hummingbirds are making little progress in their northward migrations. A series of slow-moving fronts and cooler air pushing southward have resulted in poor flying conditions. Southern observers are reporting warm temperatures and a flush of flower growth.

"First female Ruby-throat. It is warm and sunny. Citrus trees are all in bloom so the hummingbirds will have plenty of nectar from the flowers." Satsuma, FLorida 031515

"Our two Ruby-throats are now visiting the flowers and eating bugs at the feeders."
Ormond Beach, Florida 03/11/15

Rufous Hummingbirds
Rufous migration is on schedule. The northernmost sighting was at 49.7°N. Find it on the map along the east coast of Vancouver Island. When do you predict the first Rufous will reach Alaska?

"Male with brilliant flashing red neck feathers. The next day a female arrived."
Gillies Bay, Texada Island, British Columbia 03/11/15

Western Species Highlights
A break in rainy weather brought 13 sighting reports of Black-chinned hummers in south-central Texas. The places hummingbirds stop during migration are called stopover sites. These sites provide critical habitat where hummingbirds can rest and refuel.

"Two Black-chinned hummingbird males. The first arrived at 5:00 p.m. and began feeding from two feeders. He then defended the feeders from a later-arriving male. The arrival followed two days of rain." Tarpley Texas 03/09/15
