An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

These arid hills, cloaked in a mosaic of deciduous scrub and desert vegetation, form a northern outpost for several Neotropical species while also harboring several key endemics and southwestern Nearctic species. This poorly documented swallow is a breeding endemic to these high mountains. Photo by Andrew Spencer.

Many Neotropical families and genera have some of their northernmost members here, such as the spinetails ( Rufous-breasted Spinetail ), Tangara tanagers ( Azure-rumped Tanager ), and guans ( Horned Guan ). the species suffering most from deforestation). This is a fascinating area of transition. We were off to a great start.

Also known as the Flyeater, this tiny bird is the only representative of the Australasian warbler family found in mainland Asia, and very similar to my own Grey Warblers in New Zealand, even their songs. Straight off the bat we found a Little Grebe and a small flock of distant Cotton Pygmy-geese !

Brown Pelicans , and the northernmost Brown Booby breeding colony on this side of the Pacific. That larger clade is in turn sister to a clade containing the four remaining totipalmate bird families, which do still seem to be related, and which needed a new order name once pelicans were removed.

The lake was filled with families of Dusky Moorhens and Purple Swamphens (or Pukeko as we call them in New Zealand), all tending small groups of black chicks. Magpie-larks are neither magpies nor larks but are the largest of the monarch-flycatchers, and the most terrestrial of the family.
