Talk:Eurasian crag martin

Flying speed
"The flight speed has been measured at 9.9 m/s(32.5 ft/s), less than the roughly 11 m/s (36 ft/s) typical for hirundines". This is only about 40 to 45 mph is it not? This would make Eurasian Crag Martins slower than champion human sprinters. There is no context to this speed. Is this max speed in a short burst, or the average speed on a long flight, or when they are carrying mud to the nest. What is an typical hirundine? I would guess that swifts zoom around very much faster than this going on the whistling and whizzing noises of the air as they circle about. Snowman (talk) 16:18, 14 April 2010 (UTC)


 * I make the crag martin nearer 22 mph. Are you sure about your human speed, that equates to running 100 m in less than 6 seconds (this has similar to the birds)? The paper says that that the speeds are measured on any sufficiently long and straight flights, and assumed to be migration speeds, so they are averages (average migration added to article now). The paper considered four other hirundine species from three different genera (all the species available in the study area), so I would have thought that justified "typical". Swifts are not hirundines, or even passerines, so not relevant to the comparison, although the three species studied in the paper actually had similar speeds to the hirundines.

 * Birds appear to be fast, but most small birds on longish flights do not maintain continous wing beats, but intersperse flapping with glides or closed wings to save energy. The truly fast species are those like ducks and waders, large birds which use powered flight most of the time  Jimfbleak -  talk to me?  06:18, 15 April 2010 (UTC)


 * 9.9 m/s = 99 m in 10 seconds = approx 100 m in 10.1 seconds. 1700 in about 170 seconds or 170/60 mins or 2.83 mins = about 60/2.83 mph = about 22 mph. Snowman (talk) 10:58, 15 April 2010 (UTC)

Behavioural Ecology and Notes on Improvement
The introduction of Eurasian crag martin can be shortened by cutting out the information that has already been stated in the sections that follow. The contents largely follow the general format, which proceed from taxonomy, description, distribution and behavior to references, cited texts and external links. However, there are only two subsections dedicated to behaviors: breeding and feeding. The breeding section talks particularly about nesting sites, hatching process and parental care. I would add more details about how sexual selection and competition take place and how sexual behaviors adapt and evolve with evolutionary time. It may also be a good idea to add other behavioral topics like social communication, family conflicts, cooperation and competition. Lastly, the article talks about the status of Eurasian crag martin in the world. However, it might be better if the date of the datum presented was included so readers would know if the information is up to date. Tianyi Cai (talk) 12:29, 26 September 2012 (UTC)

The intro says It can be confused with the other two species in its genus, but is larger than both. But the Genus article lists four species. --Ettrig (talk) 15:13, 15 March 2013 (UTC)
