???????????????????????????????Quinta Mazatlan has been a favorite hang out for a group of Green Parakeets. We’ve seen groups of 4, 5, and 6 individuals in the park over the past week. These two individuals were busy expanding a nest cavity, with bits of palm falling out from the hole as they did their work.

The beautiful calls and plumage of the male Lesser Goldfinch have a strong connection with the heat of summer in my mind. Maybe its the bright yellow feathers, or the memories of their sweet, yet almost melancholic, whistles on those scorching hot days of past years. Either way, this little bird is one of my favorites.

Golden-fronted Woodpecker Tres Palmas

Male Golden-fronted Woodpeckers often pose wonderfully as they spend time sunning – its always a pleasure to see the golden, orange, and red colors on their heads.

The fledgling Bronzed Cowbird was being fed by a pair of Olive Sparrows. Bronzed Cowbirds are known to parasitize Olive Sparrows, but a study done by one of my father’s graduate students showed that Bronzed Cowbirds respond more to the calls of other species of bird, like Hooded Orioles and Long-billed Thrashers, than Olive Sparrows. This preference may be because Olive Sparrow nests, built low to the ground, experience high predation rates, and so it would not be evolutionarily “smart’ for the cowbirds to parasitize the nests. Still, its fairly common to see Olive Sparrows feeding cowbird young.

As always, the bird list is below. Stay cool!
