How loud?

How loud are howler monkeys? Most online sources call the Blue Whale the loudest animal at 188dB. However if you do all the rigmarole necessary to make a fair comparison between in-air and in-water noises, the BW comes in somewhere between 100-120dB. Perception to humans is also important - the Blue Whale sounds are so low in frequency, that they sound less loud to human ears. These howlers, though, really screech some.

That's a mighty fine question friend. I just tried Googling for the answer and went through about 15 pages of Google search results and can't find a smattering of data on just how loud the howlers are, except that only the Blue Whale is louder. - UtherSRG 23:57, May 15, 2005 (UTC)

The height of the howler lonkey is 4 ft!!!! —Preceding unsigned comment added by 209.175.28.130 (talk) 15:36, 8 May 2009 (UTC)[reply]

Heh. The "188dB" meme seems quite well spread on the internet, but if you actually go to the scientific sources the picture is much murkier, which is kinda what piqued my interest :). Pcb21| Pete 07:02, 16 May 2005 (UTC)[reply]

Fin whales are almost as large and almost as loud as blue whales (I've seen them quoted at over 180dB themselves). So I'd be a little surprised if howler monkey, loud as it is, managed to slip in between the blue whale and the fin whale to take the number 2 spot. Rlendog 01:22, 31 August 2007 (UTC)[reply]

The howler monkey audio recording in external links doesn't begin to do justice to this animal's lungs. That recording must have been made at quite a distance. I was once woken in the jungle of Panama by a howler monkey. It sounded like King Kong was in the jungle. 152.16.59.190 (talk) 04:21, 17 November 2007 (UTC)[reply]

There are lots of andngerge species out there that are howler monkeys that don't want to be held in captivity because it is super scary and you guys woul never think of this LET SAVE THE HOWLER MONKEY'S TODAY OR ANY DAY PLEASE HELP THEM OUT AND DON'T KILL THEM Thank You Guy's

Audio file requested

The template notes that an audio file is requested for this article, which is a good idea. I have a camcorder video of a Mantled Howler howling, but I do not know how to convert it to a file type that can be loaded to Wikipedia or to Commons. Does anyone have any idea? Rlendog (talk) 18:07, 1 March 2009 (UTC)[reply]

I've uploaded an audio file to Wikimedia Commons and linked it here. I think I'll leave the tag, though, because there's a lot of variety in the few other audio samples I've heard, and maybe more would be welcome. Teejaydub (talk) 02:51, 17 February 2011 (UTC)[reply]

Source of Humboldt quotation

The article says: 'Alexander von Humboldt said about howler monkeys, "their eyes, voice, and gait are indicative of melancholy".' This needs a reference. The passage on howler monkeys in Humboldt's Personal Narrative, Vol. 2 does not contain this quotation. Blixton (talk) 04:09, 20 June 2016 (UTC)[reply]

If the passage cannot be found in Humboldt's writings, then it should be removed outright. I will do this in a moment. FreeKnowledgeCreator (talk) 09:05, 22 June 2016 (UTC)[reply]

Refactor

Looks like we need to refactor this genus. ASM's MDD lists the species below. MDD doesn't list subspecies, but does indicate which subtaxa are included in the species. I'm concerned here with where we list a species that MDD lists as included in another species. I've bolded the taxa we list as species.

Alouatta arctoidea Cabrera, 1940. Split from A. seniculus, includes ursina (von Humboldt, 1805). We list no subspecies.
Alouatta belzebul (Linnaeus, 1766). Includes rufimana (Kuhl, 1820), mexianae (Hagmann, 1908), and nigra G. Fischer, 1813. We list no subspecies.
Alouatta caraya (von Humboldt, 1811). Includes straminea (von Humboldt, 1811), nigra (É. Geoffroy Saint-Hilaire, 1812), faunus (Illiger, 1815), barbata (von Spix, 1823), and ater (A. G. Desmarest, 1827).
Alouatta discolor (von Spix, 1823). Split from A. belzebul, includes tapajozensis Lönnberg, 1941.
Alouatta guariba (von Humboldt, 1811). Includes fusca (É. Geoffroy Saint-Hilaire, 1812), bicolor (J. E. Gray, 1845), clamitans Cabrera, 1940, and iheringii Lönnberg, 1941
Alouatta macconnelli D. G. Elliot, 1910. Includes insulana D. G. Elliot, 1910.
Alouatta nigerrima Lönnberg, 1941.
Alouatta palliata (J. E. Gray, 1849). Includes coibensis O. Thomas, 1902, mexicana C. H. Merriam, 1902, aequatorialis Festa, 1903, matagalpae J. A. Allen, 1908, inclamax O. Thomas, 1913, inconsonans E. A. Goldman, 1913, quichua O. Thomas, 1913, and trabeata B. Lawrence, 1933.
Alouatta pigra B. Lawrence, 1933. Includes villosa (J. E. Gray, 1845) and luctuosa B. Lawrence, 1933
Alouatta sara D. G. Elliot, 1910. Includes beniensis Lönnberg, 1941.
Alouatta seniculus (Linnaeus, 1766). Includes chrysura (I. Geoffroy Saint-Hilaire, 1829), aurata (J. E. Gray, 1845), laniger (J. E. Gray, 1845), caucensis J. A. Allen, 1904, rubicunda J. A. Allen, 1904, juara D. G. Elliot, 1910, bogotensis J. A. Allen, 1914, caquetensis J. A. Allen, 1914, juruana Lönnberg, 1941, puruensis Lönnberg, 1941
Alouatta ululata D. G. Elliot, 1912. Split from A. belzebul.

I propose removing A. coibensis (and subspecies), A. juara, and A. puruensis from the list in this article, and redirecting their articles to the palliata and seniculus articles as appropriate. Any data present in the redirected articles can be merged into their targets. While these species are listed by the IUCN (and the subspecies of A. coibensis is listed as a subspecies of A. palliata), none of these three have clearly been recognized as species anywhere else. Once they are listed somewhere else (preferably MDD) we can reevaluate the situation. - UtherSRG (talk) 13:59, 15 September 2024 (UTC)[reply]
