I’m the reverse! Normally need alert, normally (sorry folks) kill 8 legged critters on sight, but those itsy ones are OK!
Today saw first lesser redpoll of the year. (llinos bengoch) Only picture in shade and red on head could not be seen!
I know that envy is a very bad emotion, but…one look at that view and dwi’n teimlo eiddigedd (I feel envy)!
To @ramblingjohn Yesterday I was washing up and saw ‘our’ redpoll, but it was being bullied by the resident finches and even the siskins! Every time poor redpoll managed to land on a feeder perch, the nearest finch or siskin pecked it and it flew off again. I am very sorry to say, I suspect it will not come back to such an unwelcoming place.
Here’s a strange thing posted today on Oxford Univ’s Wytham Woods Twitter a/c (and how very appropriate that it has a Twitter a/c!) Wytham Tit Study @WythamTits 2h Here is 1 of our mixed species broods-so far the unsuspecting blue tit parents have two happy great tit chicks (blue tit eggs yet to hatch)! https://pbs.twimg.com/media/C_jvPupXsAESb5J.jpg
So are Great Tits now the cuckoos of the titmouse world?
No, it just happens sometimes that two species decide to nest in the same place at the same time.
The most remarkable piece of film i have seen concerning this, is a hen pheasant trying to move a duck of it’s nest, the duck wouldn’t move, the pheasant laid it’s egg in front of the duck nest and left, the duck looked and though oh one of my eggs has rolled out of the nest, and gently with it’s beak maneuvered the pheasant egg into it’s nest.
When the people looked at their garden camera film and saw this, they later checked the duck nest and found it contained several pheasant eggs along with the ducks own eggs.
Really fascinating stuff! Presumably only one bird/pair builds the nest in the first place (??) but after ‘mixed egg-laying’, is it simply a territorial thing with one bird establishing ownership and the other giving up, or are cases known where both end up sitting on the eggs at different times - or even maybe feeding hatchlings?

With tits, I think only one pair raised the young and fed them to fledging, probably especially proud of the big ones!! (Blue tits raising great tits). Duck and pheasants would be a puzzle! Back when, my Deputy raised hen eggs in an incubator at work where another lad was rasing ducks. He gave my lad one of the ducklings. Donald grew up convinced he was a chicken. I think I have told this someplace else on the Forum. Donald wanted to mate with the hens. His owner got a female duck, but Donald ignored poor Daphne. One day, when rounding up the flock for the night. their owner saw Donald, who never entered water, actually jump into the pond to escape being ‘rounded’. He found he could swim and kept going! Unfortunately all the hens followed him and had to be fished out and dried!! Heaven help a duck raised as a pheasant! Although that would provide a better chance of long life than a pheasant raised as a duck!
I find it all very interesting (and sometimes in a way that can be related to humans).
It gets complex because often there is one of two options, but then there are a lot of those options.
For instance, one or both sexes take part in nest building.
One or both sexes take part in nest site selection.
One or both sexes may be polygamous (given the opportunity).
Some species start several nests and choose which is best (or multiple partners).
Where males share incubation there it’s possible for females to lay in other nests.
One of the pair may be predated.
I’m sure there are other variables that i need time to think of, but i do think all options are possible, though maybe not recorded as yet, i would not exclude the possibility of two species feeding one nest of young (mixed species young or not).
One thing of note is the maternal/paternal instinct is strong in some individuals while being lacking in others (not a judgment on my part).
We may view the cuckoo as a bad parent because it plays not part in raising it’s offspring, yet, it can lay a lot more eggs than it could possible raise, by spreading them around several other birds nests, thus giving it’s young a better chance of success !
A great turn of phrase there henddraig, and a nice opportunity to than all contributors to this small font of knowledge.
Heddiw, dw i’n cael amser dda - today, i had a great time.
