Blooming + Buzzing in the Presidio: Early Spring

Did you know that hummingbird eggs are the size of jelly beans? From the ground to the tree canopies, birds in the Presidio have started actively making way for the next generation. In the coming months, close to 60 native bird species will be taking care of their young and protecting their nests throughout the Presidio.
Signs of nesting season:
  • Birds can be seen with nesting materials in their beaks and talons (twigs, lichen, spider webs, and other materials)
  • At night, Great Horned Owls are hooting their courtship to potential mates
  • Allen’s Hummingbirds and Hooded Orioles are returning to the Presidio from southern climes to start nesting
For migratory birds, the Presidio is an important rest stop on the Pacific Flyway. A variety of songbirds and shorebirds and can be spotted seeking respite and food in the Presidio as they make their way back north from as far away as South America. Throughout the year, more than 200 different species of birds find refuge in the Presidio.
Nesting species include Mallard Ducks, Red-tailed Hawks, Anna's and Allen’s Hummingbirds, Downy Woodpeckers, Barn Swallows, Winter Wrens, American Robins, Orange-crowned Warblers, California Towhees, Song Sparrows, Purple Finches, and more.
Across the park, other signs of spring are abundant:
  • After a leafless winter, willows, sycamores and other deciduous trees are re-growing their leaves.
  • By the end of spring, more than a third all of the Presidio’s 300 native wildflowers, shrubs, and trees will be blooming. In every natural area, bumblebees, butterflies, and other insects are emerging to collect nectar and help pollinate.
  • On a clear day from the coastal bluffs above Baker Beach, you might spot dolphins or other marine mammals in waters below.
