White-rumped Shamas in Thailand's tropical forests are more successful when they nest near roads--the opposite of the pattern that scientists working in temperate zones have come to expect.

Like a Fitbit for birds, these activity trackers help researchers monitor razorbill activity. Matthew Cooper and colleagues realized this tracking data could also be used to calculate the motion of the ocean. Photo courtesy of the Royal Society for the Protection of Birds

Paper: What can seabirds tell us about the tide?

https://www.ocean-sci.net/14/1483/2018/


Direction (a) and speed (b) of bird movement relative to the time of high water at Liverpool. Directions are in degrees anticlockwise from east such that 0∘ is due east and 180∘ due west. Speeds have been normalised by the tidal range on the day so that the speed shown is that on an average tide - equivalent to M2 speeds.

First discovered fossil feather did not belong to iconic bird Archaeopteryx

https://www.sciencedaily.com/releases/2019/02/190204085939.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29

Paper: Detection of lost calamus challenges identity of isolated Archaeopteryx feather

https://www.nature.com/articles/s41598-018-37343-7


Size-normalized centerline calamus-rachis traces for the primary coverts of 24 modern birds compared to the trace of the isolated feather (Berlin specimen, MB.Av.100). The blue line is the isolated feather's trace whilst the orange line is from the common magpie (Pica pica, Fig. S3) whose wing has been cited as the isolated feather's closest modern match1,7. In brown is the centerline trace from a modern Undulated Tinamou (Crypturellus undulatus UWBM 71526, Fig. S4), which belongs to the only groups of extant palaeognaths with flight capabilities. The yellow zone represents the area covered by the traces of all 24 measured feathers, including a 1.5% error zone allowing for taphonomic flex (see Fig. S1). In all cases the isolated feathers centerline is a large departure from modern primary coverts.



The isolated Archaeopteryx feather is the first fossil feather ever discovered. Top image, the feather as it looks today under white light. Middle image, the original drawing from 1862 by Hermann von Meyer. Bottom image, Laser-Stimulated Fluorescence (LSF) showing the halo of the missing quill. Scale bar is 1cm.

Species 'hotspots' created by immigrant influx or evolutionary speed depending on climate

https://www.sciencedaily.com/releases/2019/02/190206144506.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


These specimens, from Cambridge University's Museum of Zoology, were collected and labelled on the second voyage of the HMS Beagle (1831-1836) that carried Darwin to the Galapagos Islands. Researchers say these famously diverse finches are an iconic example of rapid speciation in a tropical hotspot.
