Analytics: the new powerful tool with all your stats, graphs and maps!

My Birding started out by offering a bird sighting recording system that combines automatic taxonomic updating, access to illustrations and distribution maps for all the world’s birds and direct links to all the information and materials available in HBW Alive. But we also wanted My Birding to be your best aide for planning your trips and analyzing your birding data.

To make this trip-planning tool more powerful, just a few months ago we created a series of Maps, each with its own statistics. Now we are happy to unveil a new, global Analytics page with all your statistics and maps in one place.

The Global stats option takes you to the main statistics page, which presents all of the data related to the number of species, your first sightings, endemics and your targets for each territory. Information is also given related to your photos, videos and sound recordings of species of each territory. You can easily customize the data that interests you, and put it in order following any of the columns in the chart.
You have also a link to the Maps page, with four maps:
  • Species seen of each Territory
  • First Sightings
  • Endemic targets
  • IBC materials
And in the new page, Annual evolution, several graphs visually illustrate your birding activity. For example, in the Sighted species and First sightings graph, you can see the evolution of the number of species, first sightings, cumulative species and number of sightings from your MyBirding data over the years, with a table of all the details below it. And under Sighted species per year you will find a calendar of all the years for which you have birdlists, with each day that has a birdlist shaded in blue; by clicking on a day with a birdlist, a link to that birdlist appears... So, you can easily see the years you have gone birding more often, the days you have seen the most species and much more, just by scrolling through the calendar!
We encourage you to explore and enjoy this powerful tool!

New Species from the Checklist Updated

New Split Species from the Illustrated Checklist Updated

As explained in our April Newsletter, we have been focusing our efforts on updating the passerine splits derived from Volume 2 of the Illustrated Checklist, both the original “mother” species and the resulting “daughter” species.

Over the last month, we completed the “new species” (resulting from splits) of the family Campephagidae (Cuckooshrikes) and we started on Meliphagidae (Honeyeaters). We also continue adding multimedia links to the completed “new species”, with Grallariidae (Antpittas), Rhinocryptidae (Tapaculos), Furnariidae (Ovenbirds) and Cotingidae (Cotingas) finished and Tityridae (Tityras and allies) under way.

Here are six examples to browse:
Rufous-breasted Antpitta
Rufous-breasted Antpitta
Grallaricula leymebambae
Paramo Tapaculo
Scytalopus opacus
White-throated Xenops
White-throated Xenops
Xenops minutus

Xiphorhynchus guttatoides
Pacific Hornero
Furnarius cinnamomeus

Pipreola squamipectus
Species with Multimedia Links
We keep adding multimedia links to the species accounts to increase the comprehension and enjoyment of the already detailed texts. Some of our recent favourites include links to all species of genera Asio and Ciccaba. Check them out!
Asio species
Vietnamese Cutia
Here are our picks for the “Top 5” species with recently incorporated multimedia links: White-bellied Antbird (Myrmeciza longipes), Rusty-breasted Tit (Poecile davidi), Golden-breasted Fulvetta (Lioparus chrysotis), Vietnamese Cutia (Cutia legalleni) and Mourning Wheatear (Oenanthe lugens).
HBW Alive Features
The first volumes of the Handbook of the Birds of the World series did not include the Voice section; it first appeared in the family Cuculidae (Cuckoos) in Volume 4.

We are very happy to announce that over the last month we finished the updating process of the Voice section for all the non-passerine species accounts, specifically with the completion of the last species of Alcidae (Auks), Strigopidae (New Zealand Parrots) and Psittacidae (Parrots) that where missing.

With this accomplishment, now ALL of the species accounts of HBW Alive have the Voice section completed, with the temporary exception of the “new species” of Passeriformes, resulting from splits derived from Volume 2 of the Illustrated Checklist, which we are working on now.

Here are four examples to peruse:

Analytics: a toolbox for planning your trips and exploring your birding data


As explained in the Editorial, we have created a page where all of your birding data and statistics are concentrated. Here is an overview of this Analytics page:
  • Global results box: a summary of all of your birding data.
  • Global stats: all of your statistics in one highly customizable table.
  • Sightings stats: species you have seen worldwide.
  • Targets stats: an easy way to find where you have the most target species.
  • Endemics stats: control of all one-country endemics, already recorded or still to be seen.
  • Maps: discover maps created from your bird sightings.
  • Annual evolution: several graphs illustrate the annual evolution of your birding activity.
In this news you will find a more detailed explanation of this new powerful tool.

New Taxa

Dry-forest Sabrewing Campylopterus calcirupicola

 
A new species of Campylopterus sabrewing is described from eastern Brazilian tropical dry forests occurring below 900 m asl. Its holotype (MZUSP 99024) is an adult female from Sítio Duboca, municipality of Montes Claros, state of Minas Gerais.  The new species is very similar to the parapatric C. diamantinensis of high altitude “campos rupestres” above 1,000 m asl, differing from it by its smaller size and longer light tail tips, as well as by sternum measurements.

Ringed Storm-petrel nests found at last!


The Ringed Storm-petrel (Hydrobates hornbyi), endemic to Humboldt Current waters off western South America, is one of the very few seabird species whose breeding sites have remained elusive. The suspicion was that it nests somewhere in the coastal deserts of northern Chile or southern Peru, probably in the Atacama Desert, from where there are reports of mummified adults and fledglings up to 50 kms inland. In May of this year, Chilean ornithologists discovered some tens of burrows of this species under salt encrustations in the Atacama region, near the village of Diego de Almagro, Chañaral Province, some 70 km inland at c. 26º S.
 

Egg shape related to flying abilities


Despite avian egg shape generally being explained as an adaptation to life history, we still lack a global synthesis of how egg-shape differences arise and evolve. A group of scientists led by Mary Caswell Stoddard developed specific software to measure egg shape—the “Eggxtractor”—that picks out the egg in any image and measures its length, width and shape. The team used the measurements to determine how far each egg was from perfectly spherical, that is, how pointy or elongated it was, for nearly 50,000 eggs from the 1400 species they measured. The authors built a family tree of 1000 bird species, and then discovered that each group of birds tended to have a characteristic egg shape. However, they found little correlation between that shape and the nest type, nest location or the number of young in a clutch, which were some of the previously proposed explanations for egg shape. Instead, the best explanation seems to be flying ability—the ratio of a bird’s wing length to its width. Good flyers tend to lay eggs that are more elongated and more asymmetrical, while birds that spend little or no time in the air, have more spherical eggs. The reason, according to the authors, is that round eggs require a wider pelvis than ones that are more elongated.
