Hermit Thrushes are the only species of the five Catharus family thrushes (brown-backed thrushes, Hermit, Veery, Swainson’s, Gray-cheeked, Bicknell’s) that winters in the US. Their taxonomic cousins migrate on to Central and South America.Hermit Thrushes are hardier and more cold tolerant than their taxonomic cousins. They can also accommodate more berries and fruits in their […]
An immature – yellow eyes & brown streaking – Cooper’s Hawk in our urban, deep inside-the-perimeter of Atlanta yard. This is increasingly common urban occurrence. Cooper’s Hawks are overall short to medium distance migrants. But there is growing evidence that during dispersal if a young adult emigrates to an urban setting they tend to stay […]
Birds do ‘cough’ like we do, but their coughing sounds are very different. We have diaphragms and birds don’t. When we cough, it’s our diaphragm that forces air through our vocal cords producing our deep, loud ‘coughing’ (hacking) sound. We have one larynx (voice box) at the beginning of our windpipes. Birds have a more […]
,,, or any other native fall-ripening berry plant. In autumn, many species of birds switch from an insect rich diet to including more ‘fruits and vegetables’. For year-round residents and partial, short-haul migrants this switch provides fats, amino acids, and antioxidants that help them recover from molting and prepare for winter. For the long-haul migrants, […]
This is a Barred Owl that visited our yard yesterday. Based on ‘smaller’ size, a male, I think. In most species, males are larger than females . This is called ‘male-biased size dimorphism’. Owls & other raptors tend to be exceptions. Males tend to be the smaller of the pair.There are multiple theories of why […]
It’s mid-September, the heat has finally broke, and Female and immature Ruby-throated Hummingbirds are putting on the last few grams to get them across the Gulf of Mexico. It seems that one criteria for deciding if it is time to go is they can’t see their feet 🙂 As a bonus, this is the time […]
After the flurry of spring arrivals it may seem that Ruby-throated Hummingbirds have disappeared from our flowers and feeders and the wild. This is mostly an illusion. Females, who most years out number males, spend the summer doing all the parental duties (males leave after the fun part). Moms do all that is necessary to […]
Cedar Waxwings are winter resident fruit specialists here in metro-Atlanta. But because they are late nesters & can be short-haul migrants, going only as far north as the high-elevations of the North GA mountains, they will hang around gorging on spring\early summer berry crops. Native serviceberries are a favorite. Waxwings will gather in small flocks […]
Velociraptor, or at least one of their descendants a Hermit Thrush, visiting our yard. There is consensus among many scientists that today’s birds are dinosaurs. Fossil evidence points to the theropods, a family of three-toed predators that included Velociraptor mongoliensis and Tyrannosaurus rex as the evolutionary lineage. Theropods share hinged ankles, swivel-jointed wrists, wishbones, and […]
In field guides, this species is listed as Swainson’s Thrush, with a note that they are often called Olive-backed. And a case can be made for Salmonberry Bird, at least for the population on the NW coast of the U.S. and the coast of Canada’s Inland Passage. I’m going with Olive-backed because it could be […]
