These are the relevant morphometrics to measure on a flycatcher. Although absolute measurements are very helpful, relative metrics, essentially proportions, are just as useful. These are the features that can be measured from photos or what you see, with some training, in the field.

Today for #ArtAdventCalendar, one of my personal favorite Waymakers birds, this Manx Shearwater cruising low over a turquoise ocean! 🪶 #BirdArt #SciArt
Digital illustration of a Manx Shearwater. This seagoing bird is very long-winged with a mottled brown and white head. It is skimming over the surface of the waves, and its reflection is just visible in the water below.

I love Cedar Waxwings. They’re such beautiful birds. Here’s one actually in a cedar tree! 🪶
A gorgeous bird perched on a cedar branch. It had a black mask, and most of its body is a creamy brown color. Its belly is a creamy yellow, with the underside of its tail white with bright yellow tips.

🌏🌎 Spoon-billed Sandpiper (Calidris pygmaea) 

The Spoon-billed Sandpiper is a small wader with a unique spatulate bill. Breeding adults have a red-brown head and breast, while non-breeding birds are grayish-brown. They breed on the coasts of the Bering Sea and migrate along the Pacific coast to wintering grounds in Southeast Asia. This critically endangered species forages by walking forward with its head down, sweeping its bill from side to side to sift for invertebrates in the mud and shallow water. 2.5 Flash (Edited)

No known subspecies are recognised.

Conservation status: Critically Endangered (IUCN 3.1)

We're working with the Forest Service to locate nests of Great Gray, Spotted Owls, and American Goshawks, so that forest managers can avoid nest areas when planning forest thinning and prescribed burn treatments used to reduce the risk of catastrophic wildfires.

Wagtails. Early introgression and ILS has made it difficult to create a phylogeny. The punchline is that similar looking species are not necessarily related to each other. This suggests that there was a parallel evolution of similar plumages in wagtails. academic.oup.com/sysbio/advan...
