Subject: RE: BS: Skylarks From: Stilly River Sage Date: 09 Feb 26 - 05:21 PM Paul, you're graciously responding to nonsense posted by a member who is smitten with AI and doesn't view it critically. Muscle strength in small birds may not be as obvious as in the very large ones, but as you point out, endurance is a feature for those birds that migrate. (And of course, one's imagination strays to dinosaurs as distant bird relatives, many that had massive muscles and strength.) In the New World there are a few varieties of Meadowlarks, and the ones that were always a treat to see when I was growing up were the Western Meadowlark with their bright yellow breasts. Carl Linnaeus, the great namer of things, didn't realize they weren't related to the Old World birds. From Wikipedia: As a group, the meadowlarks have had a volatile taxonomic history. When Carl Linnaeus described the eastern meadowlark (the first of the meadowlarks to be scientifically described) in his 10th edition of Systema Naturae in 1758, he thought it was related to the Old World larks, and so put it in the genus Alauda with them.[1] In the same work, he put the red-breasted meadowlark in the bunting genus Emberiza.[2] Less than a decade later, he described the eastern meadowlark again, this time putting it into the starling genus Sturnus,[1] which Juan Ignacio Molina also used when he first described the long-tailed meadowlark in 1782.[3] In 1816, Louis Pierre Vieillot created the genus Sturnella, moving the meadowlarks into his new taxon.[4] Most taxonomists accepted the new genus, and the western meadowlark,[5] Peruvian meadowlark[6] and Lilian's meadowlark were all placed in this taxon when they were later described.[3] When Charles Lucien Bonaparte described the white-browed meadowlark[2] and pampas meadowlark,[6] however, he assigned them to another newly created genus — Trupialis, for what he called "ground-starlings"; he moved the red-breasted meadowlark into that now-defunct genus as well.[7] Here is their song. |

Subject: RE: BS: Skylarks From: Paul Burke Date: 09 Feb 26 - 04:57 PM All birds have uniflow lungs and a syrinx. What bothers me is that what we were taught in school biology turns out to be stories for children. We were told that erythrocytes (red blood corpuscles) don't have nuclei (true - I've seen them), and this is so they can fold up small to get through tiny capillaries and get oxygen right into muscles. But birds (and reptiles) do have nucleated erythrocytes. I've not noticed that birds' muscles are noticeably less powerful or have worse endurance than mammals. Not many mammals can fly, but most birds can; swallows fly to Africa and back every year. |

Subject: RE: BS: Skylarks From: keberoxu Date: 09 Feb 26 - 08:33 AM Thanks to the mudelves, the top of this page has a link to Where can I hear a lark sing? thread. The only larks I have heard were American meadowlarks, as I've never been to the continent of skylarks. |

Subject: RE: BS: Skylarks From: The Sandman Date: 09 Feb 26 - 04:13 AM Skylarks can sing and breathe at the same time They achieve this due to a specialized respiratory system and a unique syrinx (vocal organ) that allows them to produce sound on both inhale and exhale, effectively using continuous, circular breathin Still posting AI (and you chopped off the end of the sentence.) Post your own words, Dick, not AI slop. ---mudelf |

Subject: RE: BS: Skylarks From: Black belt caterpillar wrestler Date: 09 Feb 26 - 03:50 AM First skylark singing this year yesterday, despite the very wet weather we have been having. Not quite as bad with us as other parts of the UK, we have had a couple of days when it has not rained, but very little sunshine. Robin |

Subject: RE: BS: Skylarks From: leeneia Date: 06 Feb 23 - 09:06 PM That's great, Robin. I'm glad your heard the skylark. In 1995, I was on a beach in Scotland, and we saw a bird flying high in the air over the nearby land, singing beautifully. I think it was a skylark. |

Subject: RE: BS: Skylarks From: Steve Shaw Date: 04 Feb 23 - 11:32 AM Well, Mrrzy, you're as likely to hear a skylark deep in central London as you'd be to hear a nightingale singing in Berkeley Square... |

Subject: RE: BS: Skylarks From: Dave the Gnome Date: 04 Feb 23 - 10:05 AM Did you know that they sing and fart at the same time. That's how they hover. |

Subject: RE: BS: Skylarks From: Mrrzy Date: 04 Feb 23 - 09:34 AM ...I want to walk the green lanes and hedgerows And feel the heart beating fierce and strong I want to stand deep in central London And hear the notes of a skylark's song... -from our very own Tabster |

Subject: RE: BS: Skylarks From: Steve Shaw Date: 04 Feb 23 - 09:13 AM That's early. I heard a great tit singing last week, and yesterday I heard the first wren song of the year so far. I do miss things due to my high-frequency hearing loss. Skylarks are on the red list of the most endangered birds. Up there in Rossendale you have lots of good open-country habitat for them. In Cornwall we have open coastal heath and short grassland which are ideal. A major cause of their decline is farming practices, not just use of pesticides which can pass up the food chain but also of the proliferation of winter wheat and winter barley (replacing spring-sown crops), which are both too tall by breeding season for skylarks to nest. |

Subject: BS: Skylarks From: Black belt caterpillar wrestler Date: 04 Feb 23 - 08:54 AM There used to be a thread about where to hear skylarks but I can't find it. I just heard the first skylark of 2023 soring upward over our house in Rossendale today, 4th Feb. Robin |
