    eBird Piping Plover June records, chromatic aberrations in small plovers and SEPL molt

    Short update as there was no interest in my requests. 1. It seems, unfortunately, that my request for the eBird team to investigate PIPL June records on Texas shore did not trigger any response. Neither I was contacted about it nor any records were removed. If eBird finds no harm with most of...

    eBird Piping Plover June records, chromatic aberrations in small plovers and SEPL molt

    Hi All, Not quite about seabirds but it is about shorebirds so it is about birdlife on the edge of the sea. After a decade of chasing Piping Plover along Texas shore from Louisiana to Mexico border, I am convinced that June records in this area are extremely rare. I only found two Piping...

    Ardeidae - hybrids in Texas

    Hi All, There are a few known instances of hybridization between heron species so if one keeps looking those hybrids are probably one’s best chance to find one. In the past 10 years I have seen three of them in Texas; found two and one was reported in an area I visit several times a year, so it...

    Common Ringed Plover with white lores and abnormal head pattern

    Hi All, In 2017 I found this oddball CRPL but, unfortunately, my plans to visit the Baltic shore (Poland) at least one more time did not work out. So here we are – a quite interesting individual with partially white lores (at bill base) and interesting black stripe pattern...

    Least Terns with novel banding scheme - flag on lower leg: asking for problems?

    I hope that all members here not only have great knowledge about banding but also are concerned about any band design/placement that might have a negative impact on a specific species. So, I want to bring for a public discussion revaluation of observations I will present below...

    RFI about existence of sham foot-paddling in gulls’ courtship

    Hi, All Gulls' lovers, I have a question for all of you who are interested in gulls’ behavior. Many gulls utilize ‘foot-paddling’ when foraging (BTW very interesting behavior to observe). But, so far, I could not find references for any gull including a sham foot-paddling in a courtship ritual...

    Piping plover

    Your best bet will be to contact Dr. Cheri Gratto-Travor in Canada (she is in charge of PIPL research there) her email: [email protected] . BTW she is very nice person, and willing to share more details than some other banders so you might learn some interesting stories if anything is...

    When Dinosaurs Ruled the Earth - Introducing Tyrannosaurus melodus

    http://www.pbase.com/mbb/image/167368974/original I think that this quiz should be very easy to all people who like and know shorebirds but I also hope that these who love this species will find posted photos interesting and hilarious at the same time. I spend countless days with these birds...

    Why to use alphanumeric flags on Red Knots that are becoming unreadable?

    Hi Henning; I just did not want to open a huge can of worms :) You did :) - and you made valid points; especially suggestion of the font is excellent. Behind the scene I was asked if I have suggestions for better material to use. I do not but I can made a suggestion how to possibly improve...

    Why to use alphanumeric flags on Red Knots that are becoming unreadable?

    I have no idea why banding organizations choose flags to use on knots (or did not stop using them) which have engrave painted numbers and letters that are becoming very hard or even impossible to read on some flags in the environment knots are living. Here one can see a few examples...

    About 2000 Red Knots (rufa) feasting on bivalves at fall stopover site on Lower Texas

    About 2000 Red Knots (rufa) feasting on bivalves at fall stopover site on Lower Texas Coast beaches When visiting beaches on Mustang and North Padre during the second part of October I estimated that there were about 2000 Red Knots foraging on bivalves in tidal zone along the shoreline on the...

    Piping Plovers banded in Canada RFI

    It seems that Piping Plovers do not get much attention from people here - I never got responses when I asked question about them. So just shortly - this Canadian fellow is just a couple days shy of being 12 years and 5 months old (13 cy) - banded as chick in 2005. Not a worldwide record for...

    Piping Plovers banded in Canada RFI

    Hi All, As I only have interest in Piping Plovers during last few years I lost hope that I ever find one banded in Canada. According to published paper they banded pipers from 2002 to 2006 using black and white flags. I could not find any in Texas despite that birds from Canada, again...

    Banded Piping Plovers - sharing observations

    Looks like interest in Piping Plovers is not so great but if interested here is a new update with over 150 new banded PIPL added. http://www.pbase.com/mbb/image/159726481/original It is a great fall for banded birds including over 120 banded Red Knots that moved along Texas shore so far this...
