24-11-2016 INLE LAKE, MYANMAR - PHEASANT TAILED JACANA (Hydrophasianus chirurgus)
The pheasant-tailed jacana's main sources of food are insects, molluscs, and other invertebrates picked from floating vegetation or the water's surface. It forages by walking on vegetation and also by swimming in water, somewhat like phalaropes (although Hoffmann claims that they wade in deeper water but never swim. It also ingests filamentous algae, seeds and plant material, but this may be purely accidental. Flocks of as many as 50 to 100 can be found on a body of water, and they can become tame and habituated to human presence. They usually fly low over the water surface but may also mob raptors higher in the air. On landing, they keep their wings open until they find firm footing.
The typical call is a mewing me-onp or a nasal teeun among winter flocks. Males and females have different calls during the breeding season, and several contextual variants exist. Young birds produce a low cheep with the bill closed.
3-10-2018 MONTE CORONA, VALENCIA - GIANT HOUSE SPIDER COMPLEX (Complex Eratigena atrica)
The giant house spider has been treated as either one species, under the name Eratigena atrica, or as three species, E. atrica, E. duellica and E. saeva. As of April 2020, the three species view was accepted by the World Spider Catalog. They are among the largest spiders of Central and Northern Europe. They were previously placed in the genus Tegenaria. In 2013, they were moved to the new genus Eratigena as the single species Eratigena atrica. In 2018, the three separate species were restored. The bite of these species does not pose a threat to humans or pets, and they are generally reluctant to bite, preferring instead to hide or escape.
The webs built by the giant house spider are flat and messy with a funnel at one end. They do not contain sticky threads. The spider lurks in the funnel until a small invertebrate happens to get trapped in the web, at which point the spider runs out and attacks it. They usually build their webs in corners (on both the floor and ceiling), between boxes in basements, behind cupboards, in attics, or any other area that is rarely disturbed by large animals or humans. They are also often found near window openings.
